Would not have clue but like you waiting for the answer so i can tell the chief who can tell the whole tribe (me).

Hi Douge, on the net there is heaps regarding design rules for lighting, including light intensities.
If you think about it, LED replacement bulbs are very bright, where as the incandescent type have a softer light. Imagine you being parallel parked on a busy road at night, and to come away from the park, you put the car in reverse. Any cars coming up to you would get suddenly two bright white lights seemingly coming towards them on the wrong side of the road. Could be very up-setting, so I think you had the correct advise.
I know that the idea of fitting daytime running lights is a similar issue, and you have to be careful of what you do.
I also went through a similar exercise to change over my brake/stop rear lights on the tug to LED. On the packet is stated for off road use only, but the salesman assured me that it would be OK. I tried one globe and tested it at night, and found that it was not only very bright, but the brake light didn't show as well as with the incandesant, so I took them back, deciding that the chance of someone running into the back of me was not worth the risk.

I do know you cannot legally use LED globes in light fittings that were originally for incandescent globes. At Least in Qld.   

 

Why I have no idea, LED's run much cooler than incandescent globes. So it cannot be a fire risk reason.  Wiring.......no they draw much less power.

 

Personally I think it's just MONEY  Buying the whole replacement LED Versions not just globes would add to the coffers of the manufacturers.

 LEDs are more directional than traditional globes, for the given brightness, and thus fittings for standard globes will not disperse the light to the required standards - just my 2c worth

I have an interesting situation on this point, and so should all Jayco owners with the round indicator lamps on their vans, when flashing, if you are directly behind the van you can see them, move off to one side, for instance a car traveling in the next right or left lane, and the lights are barely visible.
I discovered this when I found a car trapped between my van when moving over lanes, yes I did check, yes I had the indictor on for a considerable period, but Sh-t happens. So now I am going to wire in two side indicators on each side of the van, so I am sure that all motorists behind me can see my intensions.
So those lights are very directional.

By the way Dougwe, if you need extra light when reversing, I wondered about fitting an extra LED light over the tow bar for instance, wired from the vehicles reversing lights, but with a momentary on switch that has to be pressed before this light comes on, that way it is only on when your situation requires it.

Thanks everyone. I have taken all comments on board and gone away from that idea.

I am fitting a 6" Bar flood light to rear via a switch on the dash up front so can be switched on as needed and when safe to do so.

Hi Ian, the quiet period was probably due to 'doing' lunch with some great people and it took all day  

but seeing ya reckon it's none of your business I wont tell ya that 

 

Keep safe my friend.

I added a couple of those 6 inch led lights to the back of the bumper down low.
For now, theyre wired through the original reversing lights via a relay.
When I get the chance and more time, they will also be wired through a switch just in case someone complains about them.
As said, I have set them low and can adjust their angle to point down, so as not to dazzle oncoming rear traffic.
When hooking up the van at night though or off road, they get lifted up and it makes hell of a difference.
I'll throw up a pic when I get home.

 

 

with regards the supercheap advise, are we sure she's not referring to the headlight conversion to LED.

It wouldn't surprise me if they applied the same rules to the rear as they do the front, but I'd not heard of that before outside of the headlight law.

 And I am also answering IanA's message above.

The light fixtures on vehicles have closely designed lenses and some have critically designed reflectors. These are designed to give the specified minimum brightness on the required light spread. The design relies upon the light source to be the required size and brightness. If you change the light source size you are likely to the spread of light too bright in some directions and not bright enough in others.

All the common globes have tight specifications. You will find the specifications listed in  Vehicle Standard (Australian Design Rule 51/00 Filament Lamps) 2006  You will note that the scope of the ADR states

This Australian Design Rule (ADR) prescribes the dimensional and
photometric requirements for filament lamps which ensure
interchangeability and correct functioning when installed in a lamp unit.
