Just FYI:

I was really tired of breaking those damn M6 bulbs when trying to install them. For those familiar you know the hole in the lamp the bulb goes through is smaller than the bulb. So I decided to sand down the hole a little bit with a Dremel tool. Worked like a charm! The housing snaps back into place and there is no issue with moisture leaking in because the rubber seal goes to the outside of the hole. Now the bulbs can be removed and replaced without breakage!

 

I basically realized that to get them out of the socket, you have to twist and turn the bulb out of the socket, can't pull it striaght out or it breaks.

 

Even when I would twist it in about halfway the bulb would pop from the pressure. Maybe it was cold or the hole in mine was smaller, but it works sooooo much better now!

 

Okay, fine, jiggle then twist? I seriously broke one cause I tried pulling it out with pliers. The other one made it out with the jiggle-n-twist-method and is now powering the license plate light.
