I have Spyder projectors in my E53 I put in back in 2010. They work great. I used ballasts and 4300k bulbs from ddmtuning. They have a good warranty on such cheap ballasts. They are super cheap and plug-and-play, yet much better than the halogens your car came with. The I have had to replace one bulb in 5 years. I used 35w because A)those are pretty bright and B) I worried about melting things.

I never figured out how to wire up the angel eyes. I couldn't figure out an easy way to get them power and it never occurred to me that I needed inverters or another piece of equipment besides a keyed hot and a ground.
