I'm getting the kit from Emin on here (I hope!), it basicly converts the two inside (or outside) brake lights to be permanently on when you flick the foglight switch on.
When it's off, they work as normal. (I think) ie all four on, and brighter when you brake.
I thought about the reversing light, but when you reverse supposedly only one comes on because of the fog light being in there. Also, I didn't want to put a red bulb in the clear lense.
Oh yeah, I had to paint the indicator bulbs, because I couldn't find anywhere that sold the correct ones - anyone else have to do this, or did you find the right bulb somewhere? It still looks great, and gives a really bright "indicate"
