Hey, ive got a 2k New Beetle that I want to change some of the interior lights. There are two lights, one on the left and right side of my car above the backseats that i want to change. (they are the ones that automatically turn on when i open a door.) where do i buy black lights that small to put inside? (or even blue??) and how do i install those? can i just pop out the plastic cover and replace them? someone help me with this thanks!
