I have a 04 wr 450f and have fitted it with a four bulb head light. they are 4x20 watt bulbs, but i hooked it up and they blow with in seconds? So i decided to wire only one up thinking my wiring sucked, but same thing blow in seconds. I think the biggest problem is I'am dutch and bought a no name headlight of ebay. the bulbs are 12 volt rating. and i am still running the AC set up, any ideas? PS, the bulbs are house hold Halogen flood lights you would find in a track lighting system or something. I know i should have bought the right stuff to start with.
