Trunk Lid Reverse "like" lights...what are they for?

HotLap · 11-01-2008, 09:43 PM

All, checking out my new M3 tonight and noticed that what I thought to be the trunk lid reverse lights dont light up...what are these bulbs for ( the ones that look very similar to the reverse lights - but are in the M93 trunk lid lenses)? I tried all the different lights, turn, brake, parking and they did not light up......

I think you found the adaptive brake light bulbs

Are you talking about these lights?

If so they are the adaptive brake lights that come on only under hard braking. The augment the normal brake lights under hard braking.

They can also function as the rear fog lights which are standard non-US cars. Some folks have added the non-US light switch in order to be able to use the rear fogs in the US.

The rear fogs are great for very rainy days where there's a lot of spray from multiple vehicles usually on interstates. I also used them while running Watkins Glen in the rain (the car throws up a lot of spray at 120mph).

I also use them on tailgaters. It works about 70% of the time.

WOW,,,thanks all for the quick response

I can imagine how "LOUD" that bright white brake light will be under hard braking...sweet

Nice...how did you get them to illuminate...do you have the Euro light switch?

The light is actually red, just a bright red.

Yes I have the Euro switch, but that isn't my car, I borrowed the pic from the euro switch intall post on this forum.
