Thanks, 1N4148's worked fine. I made a quick vero/strip board layout since I had some around. This is for three LED's (two headlights and a cabin light) but could be extended to more -- works great.
I was going to whip up some of these lights. I don't have the stock lights to go by. Does anyone have any ideas on the capacitor values? I figure some 1N4001's would work for the rectifier.
