Re: first time motorbiker
Welcome to the forum!
Like Tom said if you use the white wire it will work but only put out 3w max and puts lots of stress on the coil. You will get better lighting from a wal-mart shelf light. Here is an upgraded version that has been on eBay for some time now. Convert from 6V to 12V and do it right. I'm not a fan of the white wire so I just cut it and use a cree light.
