This, if you want brighter lights without retrofitting I'll always recommend the Phillips Extreme Vision bulbs.LEDs make the same garbage glare that plug and play HIDs do. Either retrofit, or run clear non tinted bulbs if you like seeing. Getting a tinted halogen, especially one tinted as far as 5000k+ will make the light nearly useless.
Forgot about HIRsIf you want to stick with halogen type bulbs invest in some HIR's.
