y reg golf third brake light

hewhoisnotintheknow

This is hopefully going to be promptly answered by titheref...

My mates got a golf on a y plate, the third brake light seems to have a faint glow, this is without the brakes being applied and with the lights off

Any ideas?

Not immediately obvious.

Brake light switches can be a problem, but thats usually if the internals brake up so none would work. Taillight gasket leaking water into the electrics?

When the brake is applied, do they all light up ok?

hewhoisnotintheknow

yes all ok, strange think is it does it no matter what fuses bulbs etc i take out!

the other thing i noticed yesterday was on golfs of the same age the outer two led's on the 3rd brake light were glowing, is this a mod that people do or is that factory?

TiTheRev

Definately not standard, may be that the board that holds the LEDs has got wet and holds a residual charge? Not a common quick fix thing im afraid

I will be checking it all with a meter, if its too tricky to work out i will re run the wire to the 3rd and that should sort the issue

cheers

TiTheRev

Sound like a good idea.

Hope you sort it

They're not LEDs, they're bulbs.

Possible causes to the OPs problem:

1) Poor earth.
2) Old bulbs that've gone black.

They are actually LEDs im afraid, and only come as a complete bank, so if one goes you either put up with it or replace the whole additional brake light! Kinda rules out option 2 but could be worth checking the earths.
