thanks

I't my understanding that a 21W bulb is the unacceptable unit for a rear fog light.. (it's the same as a break light).

 

it may be the case that either your bulb or your connectors need replacement or cleaning (could just be bad contact) or it could be the wiring to your fog light.

 

I've always found external fog lamp fittings to be a problem and unreliable.. unless you fit an expansive one..

 

Alternatively, speak to phutumsch, he can mod your center light section (much easier to remove than the break/indicator sections) with extra dedicated fog bulbs.. or you could convert one side yourself.. (you will need a red colored bulb since the sections only had a clear lens.

 

I hope that helps.

 

this is an example of one of his jobs using led panels (I'm not sure if they're still available) ..

 

 

but the same can be done with ordinary bulbs... like this.. (one I did)
