I have a problem I need help with. My reverse lights stay on no matter what I do (short of turning the engine off). It stays on with or without headlights on, gear in neutral. Anyone knows how to troubleshoot?
Thanks...
mybmmer318;468117 said:Bro, check the wiring..maybe shorted. Can drive down to M&Q if u dun wanna wait a long time..
InFlames;468132 said:Where and what is M & Q? I'd troubleshoot it myself if someone could just point me in the right direction. I looked in the fuse box and none of the fuses look blown.
Electronics get me everytime!![]()

sszone;468143 said:its the wiring at your rear lights that gone nuts, not the fuses bro.
pop open your rear lights cover and see if anything wrong with the wiring.
tjy;468156 said:bro, i also highly believe is the wirings at the rear light.
this are the steps tat i will do ba... i'm no professional, but no harm trying...
1) open up the tail light cover , i'd start off from the driver's side.
2) check for any wirings that is exposed... it might be that the wire for the reverse light is exposed and pressed against another live wire?
if still cannot
3) trace out which wire is connected to the reverse bulb... trace that wire to the harness...
4) unplug the harness and take a tester (12v tester) to test if the wire that was supposed to be connected to the reverse light (linked to your car, not to the tail-light) has got electricity running or not...
IF HAVE = siao liao.. i also dunno what to do liao... it may be the line is explosed and pressed against another live wire along the way...if this is the case... i'd recommend u get a workshop to check...
If Don't have = your tail light internal wirings got problem ....
hope this helps..

InFlames;468188 said:Ok, I will try this and update you guys.
Does it matter that BOTH reverse lights are on? Which means both reverse lights just happened to short themselves, or is there a central circuit that was shorted?
wa lao... more like i'm causing accident leh.. lolx.. the rear light really damn bright.. but shiok.. haha. .tink i will just connect back the bulb to the rear fog light..sszone;468193 said:tell them u safety driver lah....make sure ppl can see u brake, preventing accidents from happening. ask them got award for being so safety-conscious boh.

InFlames;468868 said:Ok folks, source of the problem has been identified - it was the reverse sensor switch. If you jack the car up and lie underneath it it will be on the left, if you're looking directly at the gearbox it will be on the right of the gearbox. It's a small little clip. Easy fix, wiring was all fine.
I was told if both reverse lights are on then its the switch. If wires cross all your lights will be screwed up, depending on which are the wires affected.
One more for the record.
