Is it just the lens that everyone puts in or is it enclosed with a hid bulb with a harness behind it? Im looking to put in projectors in my car thing is Im not sure if its just the lens that everyone puts in or is it more than that? and where can I find cheap projectors like $50 bucks.

 

It is very hard to find them for less than $100 per set, alot of information is here:

for $50 you'll only find halogen projectors...
