Had my interior light do if it's for a k10 with a sunroof "some have a circular light!" If you push the bulb in and lean the connector outwards, you can jimmy it in! Works wicked had it done early on and put the bulb in his clio! Best bit on the car ;-) i replaced mine with a superbright one and it really does put a bit of light out!!! Think they normally come in two sizes mm it's the smaller of the two!!!!
