I pulled my headlight and tail light off of my 05 wr 450 a couple of years ago. I went to hook up the headlight a while ago and after starting it, the bulb got super bright and blew out. I bought another bulb and the same thing happened. I talked to a guy at the Yamaha dealer and he said it might be happening because the rear tail light is not connected. He thinks that it might need to be a fully connected circle (but wasn't sure). Does this sound true? Electrical is not my thing!!!! If this is true, is there an after market rear fender/light that isn't as huge as the OEM version. I like the new wr tail light, but I don't think they will fit.
