Ok, I think I can forget about soldering anything - don't have the equipment and/or know-how to know what I'm doing with all that.
Secondly, the lights were purchased secondhand, so no instructions either. The light is already set up - lights are mounted and wires come through in the middle. So I assume it's just a matter of bolting the kit on the bike frame and then connecting up the wires. How hard is it to remove/reinstall the gas tank?
Be advised, I've only had this bike for about two months, and this is the first time I've ever worked on one. Thanks!
