I figured a short circut would be blowing fuses but they seem o.k. and I haven't had to replace any. I've put 4 bulbs in this thing in less than 3000 kilos and that seems like a lot to me. > Any thoughts? > Steve Pye > A7 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Steve, The most common causes of premature bulb failure are excessive voltage and/or vibration. You can probably rule out too high voltage because you are not complaining about other bulbs failing also. The best check for proper voltage is to ride your bike (at all rpms) with a volt meter temporarily hooked up to your electrical system and seeing if the voltage exceeds 14-14.5 volts. I would hook up the positive (+) lead to the brown wire that feeds power to the headlite switch. The negative (-) lead is is attached to the black/yellow ground wire. Excessive vibration can occur if the headlite assembly and/or bulb is improperly secured. Make sure that there is no 'wiggle' in the H/L assembly and that the bracket that holds the fairing and H/L is secure. The bulb should be securly attached to the reflector by the H/L spring. I have found that retightening all engine mount bolts every 2 thousand miles helps to minimize overall vibration. Q1? Are you using el cheapo, mongrel brand bulbs or major brand name bulbs (Phillips, GE, Osram, etc). Q2? Are you touching the bulb's glass with your bare hands? It is a no-no to ever touch a halogen bulb's glass with your hands, as this will lead to immediate or premature bulb failure. BTW, a short circuit will not cause bulb failure, blown fuses or melted wires, yes. Professor A9 Federal Way, Wa. [USA]
