well I dont know personally about LED head lights besides some new cars come standard with them. You would want to run a projector cause it has a cut off line, that limits the light from going All-over the place and blinding other drivers! There are many types of projectors and NOT all the same quality! ALL depends on what you want, Low beam only, Bi-xenon(HI & low beam), and then how good do you want your headlights to be and how much are you willing to spend and do.
Id just browse and look at what you ARE willing to spend, and when you say you want it Brighter, what you mean by that and what will you be happy with. To maybe give you an idea, (depends on if you do the install and labor yourself) but basically MY take and opinions to how headlight lighting is in a nutshell: (sorry i dont know WB pricing or products) NOTE: THIS is MY opinion and basic idea of the HID market, some will beg to disagree (not saying im right) so always do your own Research!
$0-$100 (replacement Halogen bulbs, like silverstar bulbs)
$100-300 (cheap projectors and ebay headlights)
$300-$450 (good set of projectors)
$450+ (best, OEM projectors and luxury projectors)
