Well my LED turn signals for my tube fender project came in the other day, and I got bored so I made the 2-3 wire converters today.
The converters all heat-shrink wrapped.
I will be powering one triangle light and one circle light off the same converter on each side, so I went with 3 amp 400v diodes and 1 watt 100ohm resistors. Works perfect! Been running the lights for about 2 hours on "running light mode" to test how hot the resistors get. Not even warm.
Also modded my flasher relay, but it's still a bit fast so I think I will just get the EP-26.
