light burning out

[ignelioo]

my slider keeps burning its lights out. I have a fair setup, everything is good, but when i ride and my front light is on 2 min after the light burns. I tried another light, and set it on long lights, after 1 min of riding it burned out, what can be the problem?

You may have a bad regulator/rectifier. Try checking voltage at the bulb socket to see if it's getting too high when revved.
