Hello guys i'm new in the bmw world but have had vetts im sure this question has been ask a hundred times i don't know where to go look for it qwestion i have a 2008 550i m sport i think i won't like to do something to the head lights i see about every body installs angel eyes but the big big question who's got the best not so much the price the BEST thanks you guys have been so helpfull

 

It depends if you are willing to 'open' up the light housing and install Orion rings. Those are the absolute best, but a professional will have to open the light to get access to them. If that's too much risk for you an HID application will likely be your best bet. Vendors on the site can help, but it's your decision whether opening up your headlights is something you're willing to undertake.

 

Orions are a lot of work and expensive. HID kits burn out and sometimes melt the wiring because of heat build up. I went with 12w LED AE's from Trinity Autosport (members Nerweezy and Trinityautosport) they are bright enough to be seen during the day and require no additional wiring or ballasts to make them work AND you don't have to open your headlights.
