Thread: tralier light flashing when blinkers are on

Just about everybody replaces the bullbar indicator globes with 5W or 10W globes and the problem is solved. There's no black magic to it.

Problem solved!

Good to hear that works!
I was thinking that the current draw of the relay would be enough to trigger the trailer light.

On the flipside to the original problem I actually want to make my trailer indicator work. I have to buy a new flasher can before I can get around the extra indicator current draw problem

Common problem the LED replacments in the bullbar fix it - ARB and TJM should bloody well know by now they have fitted enough on Discos.

Sorry Ive peraded the fact that im getting a bar lockers etc so much I assumed the world knew

Ill go with the LED lights in the bar as I dont want to disable the trailer light for trailer use

[quote=Blknight.aus;614858]if you get a high resistance in the blinker circuit or hang extra lights off of it the trailer light will blink in tandem with the indicator light.

Apologies in advance if you think this is nit-picking but slight correction there, Dave ...
... if you get a low resistance in the blinker circuit ...

I think it is important to know whether a trailer indicator has blown, so agree with the LEDs.
You can buy straight replacement bulbs that fit into a normal bayonet socket. ( but who knows what ARB have put in the bar)LOL.

The dash light blinks to let you know that your trailer indicator is working. IE. No dash light when trailer attached = trailer light is blown.

Thats weird that ARB did not have the LED lights for the bar. Got one in Brissy last year and it was standard fit from ARB factory with LED.

It's perfectly normal and as far I know and the trailer light on the dash that blinks with the indicators makes the driver aware that there is a trailer attached and to be aware of that when turning.

ARB should have known this but they probably have some twit fitting accessoried who only knows how to plug in a rattle gun.

On our Disco we have a TJM bar and the fitter installed the lights the wrong way around. The parking lights had been fitted furtherest to the outside of the bar. It was a simple matter of turning the fittings 180 degrees.
