Yep voltage regulator. My headlight and taillight used blow up, put in a new volt regulator and have not blown a bulb since.

$150 posted off eBay for OEM plug and play,

$115 from rocky mountain (postage would be a killer though)

I imagine you could get a generic that would work aswell, after all a regulator is a regulator but you would need to ensure you found one with the same specs.
