Sounds like you have too much voltage coming out from your battery, mabey a faulty regulator. The easiest way to test this, is to get a multi - meter, and check the volage output at the battery, with the engine running, at idle should read about 12.5 - 13 volts. Then rev the bike up, and seeif the reading changes, it should not go more than 13.8 or 14 volts max. If it does, then i say you have a faulty regulator/ rectifier.

Have a brand new jonway 50cc 15 miles blew bulb whats wrong

Occasionally bulbs will fail for no reason. Replace the bulb and try again. If it fails again, then you likely have a problem.

My headlight keeps burning out on my znen tommy 150cc scooter every few days i have to put a new bulb in WTF?

hi,sounds like your voltage regulater has failed,it is supplying to much voltage to the bulb and causing it to burn out,if you dont have a voltmeter take the bike to a garage and check the voltage ,with the bike running at about 2500rpm,the meter shouldnt read more than about14.2-15.0v,if it does,that means it is faulty,hope this helps...cheers

Try to put a relay on every bulb to prevent burning, and also check the bulb socket make sure it is not loose.
