I've had Diode Dynamics LED bulbs in every light socket on the truck, interior and exterior, other than the stock fog lamps, and am very pleased with them. They can help you decide which bulbs to get regarding locations (headlamps etc).
Just do what Laps said. I've used DD for years in multiple vehicles. You can't beat the quality. They're pricier than the trash you can get on ebay and amazon but totally worth it. Also, you can't beat the 3 year warranty. 9012Ram is the headlight bulb size for the projector housings. Seriously worth the money. Their site will walk you thru size choices for the Rebel.
