I have a stock 02 wr 125 and everytime I install the headlight the bulb will turn on (with bike running) then blow after about 20 seconds. It's the correct bulb from dealer. And it cost about 15$. I was curious why this is happening? And if anyone has tried one of those cheap headlights I've seen on eBay. They are around 50$.
Yes, I checked the wiring diagram as well. Yellow connects to it an the same yellow wire comes out an connects to the head lamp
