Hey guys,

On the trunk there is a light on each side that look like brake lights or something. I have heard them called "rear fog lamps", but am unsure of what they're really called.

My question is, how or when do these lights turn on?

Thanks!

They are rear fog lamps ... they are not installed on US equipped cars, hence forth you can't turn them on.

Thanks for the info.

That's a bummer. :(

Some people have done a retrofit. Can remember all the details, but I believe it involves some wiring and a new LCM (LCM has 2 separate fog light switches).

At worst, I would imagine you could tap into the front fog lights wires and run an extra wire to the back.
