Keep burning out the left side headlight bulb

My Stelvio keeps burning out the left side head light bulb, anybody else have this issue?

Any thought's on what might be causing it?
 
Same as Wayne with 1K fewer miles. Are you running a jumper to both lights? Just a few common causes to double check, but taking care not to "touch" the new bulb's glass surface, relays and proper gauge wire and the assembly has no damage or is loose that would allow undue vibration to fatigue bulb. I would also put her up on the stand and with the bike running, try the ol tug and pull :shock: and turn the bars back and forth while looking for any intermittent loss of lighting caused by problems in the harness/connections. Based on the routine of repeated failure it's something basic, but chronic that is stressing that bulb.

Good luck.
 
It may pay to check the voltage at the bulb connector with a multi meter. If you have a poor connection (somewhere) and the voltage is reduced this has the effect of increasing the current draw from the bulb, burning them out sooner.
