I used the b8 style on the instrument cluster and the neo style on the hvac. The first ones I got on eBay where **** quality didn't fit. I ended up disassembling those and soldered some of those in for the hard wired bulbs. I made my own bulbs out of the old factory ones for the hvac cause I was bored. Ill admit even the bulbs from superbrightleds.com don't fit perfect. They where a little loose and I just had to tweak them a little so they fit snug. This is def a fiddle mod. Of you're in a hurry don't do this mod lol. It was fun though I enjoy soldering and what not so I liked it. My over head used smaller bulbs so I just removed those for now and only put the film in. I made the accent lighting again with some of the spares I had, and wired them to the cuff outlet do they come on with the key.
