    Sounds like either your voltage regulator is allowing high voltage (should be no greater that 14V or so max. OR the bulbs you are using are not heavy duty 1157 (dual filiament) bulbs for rough service (yeah we luv the way our V-Twins lope don't we, one potato at a time).:D May also want to check the connections for corrosion or signs of arcing.

    Are you using a heavy duty bulb or the standard 1157 bulbs.
