I agree with GREG, the LED's require the Elctro-Gizmo-Whatchama-Call-It. I put some LED bulbs with out it and it Blinked liked crazy and didn't look that great. I am back to regular bulbs, but I opted for the POLARG brand, they are a little brighter and look really clean. I do however have the LED for Reverse and it looks tight and alot brighter, it has a black light hue to it. I loved them so much that I bought them for the interrior Dome and map lights.
