LED lightbars have been popular over recent years, but as ever the road authorities across Australia have been slow to amend the rules – where can you legally mount LED lightbars?

The first principle of vehicle modifications in Australia is that the answer is always state-specific.  Sadly, each part of Australia has its own road authority, which has a slightly different set of rules so what’s legal in one state may not be legal in another.  Because, well, who knows.  We just have to live with the pain.

LED lights are popular because they’re relatively cheap, provide a nice, white light, are small and easy to mount relative to conventional driving lights.  And they look cool.   LED bars are not a subsitute for spotlights because there’s just not enough room to design a reflector which can throw light a reasonable distance, so instead they’re best used as short-range fill lights for manouvering, low-range driving, recovery or working.

The law used to state that all driving lamps had to be mounted in pairs so that the lighting was symmetrical.  This made sense for the conventional circular lamps, but not for a light bar which while a single light is so broad it can be mounted symmetrically.   Eventually, the appropriate Australian Design Rule (ADR), number 13/00, was amended to permit use of lightbars provided they were “fitted to the front of the vehicle, symmetrically about the centre”.   However…they didn’t specify a minimum width or height, so you could have a very short lightbar and technically still be legal.   Wouldn’t recommend pushing your luck though.  At least now all states and territories permit lightbars, so we’re all good now with consistent regulations?

No, that’s be too easy.  Below are some excerpts, and the bold text highlights some inconsistencies:

Here’s Vicroads’ official words on the subject:

  • The lamps should, as far as is possible, be installed symmetrically in pairs to the front of the vehicle. 
  • If lamps are not fitted as pairs (e.g. one, three etc), they must be fitted to the front of the vehicle, symmetrically about the centre. 
  • A maximum of four driving lamps (including LED light bars) can be fitted to a vehicle in addition to the vehicle’s main beam headlamps.
  • The lamp/s must be installed in a way that the light produced does not cause the driver of the vehicle discomfort either directly or by reflection. 
  • The lamp/s must only come on when the main-beam (high beam) headlamps are used, and must automatically turn off when the main-beam headlamps are turned off.
  • The lamps must not obstruct the driver’s view of the road.

What about SA?

LED Light Bars and additional headlights may be fitted, provided that they meet the following requirements:

  • The light or lights must be installed to be forward facing and in a position that does not obscure the driver’s view of the road ahead.
  • The lights should, as far as is possible, be installed symmetrically in pairs of between 2 or 4 lights.
  • If the lights are not fitted as pairs, they must be fitted symmetrically about the centre line of the vehicle.
  • The lights may be fitted to the roof of the vehicle.
  • The light or lights must not be fitted or be used in any way that is likely to dazzle another road user and must be installed in a way that the light produced does not cause the driver of the vehicle discomfort either directly or by reflection.
  • The light/s must only come on when the main-beam (high beam) headlights are used, and must automatically turn off when the main-beam headlights are turned off.
  • The driving lights may be fitted with an isolator switch to allow high beam to be switched on without the driving lights also being switched on.

And here’s WA:

The exemption is subject to compliance with the following conditions:

  • The LED light bar(s) must be installed at the front of the vehicle and not higher than the front
    edge of the bonnet.
  • The LED light bar(s) must be installed horizontally and located symmetrically about the
    longitudinal centre line of the vehicle.
  • The LED light bar(s) must be forward facing and positioned in a way that the light produced
    does not cause the driver of the vehicle discomfort, either directly or by reflection while in the  normal driving position.
  • The LED light bar(s) must only operate when the high-beam headlights are in operation and
    must automatically turn off when the high-beam headlights are turned off.
  • A manual switch must be provided to allow the LED light bar to be deactivated, so that it is
    not on whether the high beam is on or off. This switch must be accessible to the driver of
    the vehicle from the normal driving position.
  • The LED light bar(s) must only emit white light.
  • The LED light bar(s) shall not obstruct the driver’s view of the roadway more than 11 metres
    ahead of the driver’s eye position when looking through the windscreen, with the driver’s
    seat in the rearmost position
  • One or more (to a maximum of four) LED light bars may be fitted as additional driving lamps

And they have another:

Queensland has a similar take on it here:


which includes:

Driving lamps may be fitted above the roof line. The driving lamps must be fitted to the front half of the vehicle, when measured from the front to the rearmost point of the vehicle.

however, it goes on to talk about not increasing the risk of pedestrian injury, line of sight of the driver and so on.  That means the above statement is not a license to install the lights wherever and however you please on the roof. It also specifically mentions protrusions.

Enough! What does all this mean?

The rules excerpts above all more or less say the same thing, but every authority has put their own slant on it.   One problem is that absolutes such as “you will not mount lights on your roof” (unless you’re in WA) have been replaced by “do not dazzle another road user” and “cause driver discomfort”.   This is good because it gives freedom of placement, but bad because it’s hard to define what dazzling or discomfort is.

So, below I’ve written a conservative interpretation based on reading the above and other sources which appears to comply with all the states’ various demands.  But as I’m not transport minister, it’s not law so use at your own disrection and as guidance only:

  • Number of driving lights – maximum four.  This may be 2 x pairs of spotties, 4 x lightbars, 2 x spotties and 2 x lightbars.  The rules are clear on this.
  • Mounting – symmetrical relative to the centreline of the vehicle, even if Vicroads have poor wording.  Rules clear here too.
  • Switching – driving lights only able to be switched on with full beam, and full beam must be operable without the driving lights.  That seems to be safest and is what most people do anyway.
  • Orientation – long side of the lightbar to the horizontal.
  • Location – no higher than the car’s headlights.  If you do that, then there shouldn’t be any drama with arguments over dazzling other users, discomfort and so on.  You could perhaps mount higher legally, if you’re prepared to handle the dazzle/discomfort issue.  The actual words from ADR13 are “illuminate the road ahead of the vehicle without causing undue dazzle or discomfort to oncoming drivers and other road‑users”.
  • Direction – forward facing.  Best to make them all exactly forwards facing or very nearly so.
  • Obstruction – no part of the light visible from the driver’s seat.  Then no worries about obstructing forwards view.
  • Light colour – white.

So far, I’m yet to hear of anyone having compliance issues if the above list is adhered to.  Oh, and don’t forget to allow adequate cooling space too.

Dear Road Authorities of Australia – feel free to copy the above as standard wording.

A quick note HID (high-intensity discharge) headlamps

Can you upgrade your headlights to HIDs?  Yes, if you do it legally?  That means you also add:

  • an automatic headlight levelling device
  • headlamp cleaners

You’ll also need to redesign the reflector so that it works properly with the HIDs.  Basically, the effort isn’t worth it and if you want more light then fit a set of spotties.  More on this in Australian Design Rule 13.

  1. Well done Robert. Plenty of research has gone into this article. I don’t own a SUV/4WD but I have been seeing more of these light bars fitted to them. At times I wonder whether owners are fitting them for a practical purpose or because they look interesting. It is annoying that the laws vary from State to State.

  2. So I got defected in my Nissan in Richmond NSW, only last week. He claimed I was given 7 days to remove and get the defect cleared($100) or I loose my licence. I’ve no doubt the RTA will charge me a fee also. Angry Wendy

          1. However….the ADR does NOT say the lights must be mounted on the “FRONT END” but :
   In length: AT THE FRONT of the vehicle and fitted in such a way that the light emitted does not cause discomfort to the driver either directly or indirectly through the rear-view mirrors and/or other reflecting surfaces of the vehicle.””

            ADR ALSO SAYS:
            “ In length: At the front of the vehicle. This requirement shall be deemed to be satisfied if the light emitted does not cause discomfort to the driver either directly or indirectly through the devices for indirect vision and/or other reflecting surfaces of the vehicle.”

            i dont know of any other legislation on this, but others may be able to advise further.

          2. Hi Nicole, I went thru all this with the RMS guy. My light bar is turned on by an isolated switch. In the 3 years it’s been on the car it has been used maybe a dozen times, in the bush on private property usually or in the thick of the bush setting up camp. It doesn’t protrude outside of the vehicle area and so poses no risk of injury. All I want is to be presented with the regulation that states this is illegal. That states about roof mounting.
            Nobody can seem to do this. The regs are muddy at best. Nothing is clear in writing.

          3. It’s says here as a requirement the must be on the front of the vehicle. I don’t see how that isn’t clear?

          4. Because, as I was pointed out by the Sergeant that defected me, ‘ The front of the vehicle is designated by the door seam at the drivers right shoulder’. This is forward or front of the vehicle.
            Thanks for your time btw

          5. Graeme Snell from RMS explains the ADR13 rule. He says whilst there is no height limitation the requirement in ADR 13 7.3.4 is for the lights to be at the front of the vehicle. This would limit the placement for example on the roof or roof rack. The ADR definitions define front end FRONT END / the foremost point of the vehicle including the bumper bar;over/riders;tow hook; and bull bar if standard equipment. He also stated that the ADR13 has been amended and the last past states ” are fitted at the front,symmetrically about the longitudinal centreline. If you look up a pic of what longitudinal and centreline means you’ll see a pic. Here is the federal register of legislation and the full act is available to read.
            Hopefully this will help as it has been a mind field for me to research as I’m sure it is for a lot of people.You will see the reference to ADR13. https://uploads.disquscdn.com/images/c8313ee1011649f216459e0a5614c587a085b2123b24f4fa67fc0990eff04fd8.jpg

  3. One of the old laws does state that lights must not be fitted above 1400mm from the ground on a vehicle …so most 4x4s wouldn’t pass this with the lights on the top of the bullbar yet alone the roof …

  4. An interesting read, thanks Robert and the other contributors.

    I’m in Victoria, and have a Jeep Grand Cherokee Overland with a bullbar, which has a pair of HID spotties in the middle above the winch.
    I have been trying to save up for some Light bars, and now I’m not 100% sure if I should get everything planned and risk it, or not.
    My plans are a pair of 12″ spot/wide bars mounted on top of the bumper bar section, at the ends, just below the headlights. I want some illumination closer, and to light up the forward sides so I can see any obstructions, or animals to the side of the track/road.
    And 20″ – 24″ bar on the top rail of the bullbar. Mostly for some range, but also to light up the front, in order to light up the track directly in front of me, to see obstacles in time, and to allow me to avoid obstacles and wildlife. As my bullbar has an antenna mounted to the left of the bar, I don’t want it to sit behind the antenna as the chrome bits, such as the spring would cause a reflection back to me. Also if the light is too close to the antenna, I’m concerned that it could interfere with the reception, and possibly reduce the range of the CB radio.

    The other thing that is now concerning me is I am in the process of setting up some accessories, which includes a pair of led lights mounted in the rear bumper, and which are switchable, and come on when in reverse. We have a caravan, and having the ability to light up the rear, should make it easier to to reverse, especially when parking the caravan, and when reversing to hook up the caravan. The car has a well positioned reversing camera, which shows the tow ball, and allows me to see exactly where everything is, and I can hook up the caravan without a need for a spotter.
    The lights will have an overide switch, so I can have the lights on when in Park, so I can see the rear of the car, and help me hook up a snatch strap, when helping to recover a stuck vehicle behind me. Or to level and setup the caravan. Or to organise luggage when setting up our caravan, or packing up. I hope that this won’t be an issue.

    Considering the roof mounted lights, I see a lot of 4×4’s with roof mounted lights, both spotties and light bars.
    I can’t see any problems with lights mounted on the roof, or having more lights than allowed as long as they aren’t used on the road. The only reason in my mind that lights mounted on the roof could be an issue is that they raise the clearance of the vehicle, and the car may not be able to fit into a standard garage, or car park, but as long as the driver knows the height, then he/she can avoid attempting to park where the clearance prevents.
    The ADRs from what I believe are for road use, but when going off road, I can’t see how the same rules apply. A lot of these lights state on the box, and some on the actual lights as well, that they are not suitable for use on public roads, or that they are only suitable for off road use only, so in that situation, as long as they don’t cause an obstruction to the driver, then it should be ok.
    It’s all confusing lol.
