I'm guessing you've never called their tech line. :p

@slantsixdan is more passionate about lighting than most of us are about Mopars. It's his consuming passion and life's work. His recommendations are spot-on, so if you really want to upgrade I'd suggest contacting him. He's very helpful and friendly, and there's never pressure to buy from him. His attitude seems to be "I am going help this person. If they happen buy something, bonus." In fact, he recommended I try a relay upgrade with halogen sealed-beams first, before committing to the Koitos I bought from him for both my Challenger and Valiant. His expertise and assistance is well worth the expense.
