Any suggestions where I can purchase H-3 35 Watt bulb for Triumph light bar? Purchased 55 watt bulbs at local auto parts store but the battery is severely drained, and tonight almost got stuck with a dead battery.

I thought this 55 watt bulb could be a problem but found out tonight. I was so psyched to go out on this extremely warm October night. I drove home with light bar off and battery was fine. Found a few places on line but would rather purchase at some local auto or other store. Triumph dealer does not have in stock.
