They are nice, they also will probably blink fast, kinda like when u have a burned out turn signal, this is because the leds take less current then standard bulbs, the relay thinks there burned out, you need to place a load equalizer inline with the postitive side of the wiring harness, this tricks the relay and will blink normal, but just brighter and more crisp ( faster on/off times) see if this helps also check out superbrightleds.com that were I order mine from they have alot of good info there on everything you can think of for leds.
