Hi, I was replacing my rear tail light (blue arrow) and noticed that the pink bulb wasnt working on both sides and saw in this picture that there is no bulb at all and in a video on youtube there was no bulb, is there a reason there isnt a bulb there on other cars or why neither of mine work?

Its probably the fog light, stick a bulb in it and turn on the rear fogs and see?

I agree that it is the rear fog light. You have to pull the light switch out to the second detent to make the rear fog light turn on.

I would guess the reason they only put a bulb in one side is so that cars behind you don't think you're braking.

The rear passenger fog will not come on by design..it only works on the drivers side...

Rear fog. your fine. It'll work on the passenger side, but I wouldn't do it. Makes it look like your brake light are stuck on.

Only one or the other side will light, depending on which side the driver is on.
US rear fog is on the left only.
It might be able to be programmed, but I think only one side will light either way.
