headlight recommendation for my Duster

Dang the cost of LEDs. Just do an H4 conversion. Get some good quality E code headlamps and some GOOD bulbs and install one of @crackedback's relay wiring harnesses. Remember, LEDs in our old cars are probably illegal in all 50 states. Not that that stops people from doing it, but the chance is there for a ticket and I bet it wouldn't be cheap.
