Let there be Light
While back in Victoria for Christmas, I installed an LED headlight replacement bulb for the quatrz halogen light that originally came with the new headlight. As mentioned before, the charging system on older Harley Shovelheads just can't keep up with the current requirement of a quartz halogen light. The older systems only put out 15 amperes at best so running with the headlight on for extended periods of time tended to discharge the battery. A halogen bulb draws about 4 amperes whereas the new LED bulb draws less than an amp. Now, with the bike turning over at about 2000 revs, the battery maintains 13.5 volts. An added benefit was the brightness of the new light ... wow...that thing is BRIGHT!!
