Replaced the tail lights a few months ago... the lights were always a bit intermittent, so after 200$ of factory lights from Car-Parts.com

I found that the tail lights had actually melted due to poor ground... unfortunately I made the mistake of using bulb grease when I put them in. Sometimes they worked sometimes they didn't. Went out and bought a tub-o-towels and gave everything a good wipe down and got the bulb grease of there and they work like new! DON'T USE BULB GREASE
