Hi Guys,

Noticed today that my rear lights (bottom one) are different brightness levels, passenger side is VERY bright, drivers side looks alot dimmer, tried swapping bulbs and fitting new ones, nut they are still the same ?, any thoughts why this is.

Have looked at the bulbs when lit with them out of the lenses and the passenger side one has a different element lit to the one on the drives side ?

It's got me baffled :confused:

I think the bulbs are double element, as one will be for the fog lights, and it might be possible that the brighter one is lighting the fog light element instead (only one side lights up for the fogs, but both bulbs are double element as standard).

Sounds like yours are around the wrong way, and the fog light bulb is on the wrong side (might find the rear fogs don't work).

Put the one with the two elements on the drivers side, then if the problem is still there, try rotating 180degrees.

HTH, Joe

Thanks for the suggestion Joe, I've just nipped out and switched the lights on and as I said the passenger side is very bright, drivers side looks dimmer compared to it, pulled the dial to put the rear fogs on and they are both the same brightness so it looks like the passanger side foglight is on all the time ?, will check the bulbs tomorrow and see if I can put them in a different way (from memory I don't think this is possible as the pins on the sides are at different depths I think ?

Still confused !

Hi Alan

As standard the nearside fog light does not have any wiring to it, so cannot be the fog (unless rewired)

Could this be the same problem that the MKIV Golfs get?

See it all the time, but I'm not clear on the cause. Is there an earthing point for the rear loom somewhere (I would have though it's be the main one by the fusebox so not relevant).

Maybe check any nearby loom connections - clean off any corrosion, apply silicone grease and refit?
