Yesterday after work I went to replace my headlight and take out the modulator on my motorcycle. I removed the modulator, and soldered the wires back together. Just for kicks (to make sure things were correct) I plugged the old bulb back in and turned it on. The high beam worked just like it did last night, and the low beam... worked. The bulb didn't go bad. So was it the modulator, or a loose wire? The kit used crimp on connectors, so now I'm wondering if it would work fine soldered together. That does mean unsoldering what I did yesterday and putting the modulator back in soldering each of the connections this time. So should I do it, or keep it out?
