2003 wr450f headlight problems

I have a 03 wr450f and my headlight is super dim when idling (can't even see past front fender) and as soon as i start going the light seems fine for a couple of seconds then the bulb blows i changed the rectifier/ regulator same thing is still happening can someone help me out please

 My first guess would be a regulator/rectifier, but since you already replaced that I would think either some wires might be crossed or possibly a problem with the stator or coils.


 That is a weird problem. Hopefully one the electrical gurus on here might have some ides.


Good luck, Keep us posted.
