lol this is probably a dumb question but anyway i took out my rightand left taillight to get some crud out. i took out the bulbs and put them back in when i was done. now the 4 bulbs that are closest to the trunk are not working. i thought i broke the bulbs but when i put in new bulbs they still wouldn't light up. anybody have a solution to this.

 

Did the crud look like peanut butter? That is a conductive grease that provides a better connection from harness to bulb. It also acts as a way to secure the bulb.

 

the crud that i am talking about was on the corner of both the taillights. where is that conductive grease located? is it around the bulb hmmmmm ill check tomorrow
