You need to be more specific. Also, if you run a search, you will definitely find a lot of information about headlights. In fact, right at the top of the E36 section there is a thread dedicated to headlights/angle eyes, etc. If you want a killer upgrade, then you need to get ellipsoid headlights, which means you will have to change the entire housing. That is expensive, but you can then get HIs/Xenons. Umnitza is a good place to get this stuff from. You will get a better spread of the light. If all you want to do is replace the light bulbs, you can get Silvania Silverstars. That would be cheaper, a decent upgrade, and you can even finde them at Wal-Mart.
