Yamaha WR200 headlight

[cooldude3552000]

Hi, my bike is a wr200 and it has a stock head light and tail light. Acording to the yamaha parts page the head light is 12v and 36w. The head light is pretty bright but I wanted to know if there are any better bulbs I can put in it to make it a little brighter. I don't want to replace the alternator, just wanted to know if there is a better/brighter bulb that will fit.
The alternator seems to have plenty of power because at idle it dims a little but when the gas is on just enough to move the bike the light brightens up to full power.

Thanks,
Colin
