My blinkers have gone from hyper-active back to stock blinker-flashing rates! Yay!

And all it took was unplugging the factory blinker relay and plugging in the new LED relay that I bought from CustomLED (http://www.customled.com/products/elfr- ... sher-relay). No splicing, no stripping wires, no mess - absolutely plug-n-play. Theoretically, this same LED flasher relay should work with the pre-1997 XJ's that have the three prong factory flasher relay, but I haven't tried it out on one.
No, I didn't make any horsepower, but it sure makes the bike feel a lot less red-neck rigged.
