Turn signals option USA in EU

[Lord Popgun]

Dubs, I think we went through all this last Winter trying to help someone hook up LEDs. He could not get them to work in the front. Ultimately he hooked them to the rears, or some such,

I, wondering what was going on, metered the voltage and saw there was ~4.5v IIRC on signals when running lights were on. Since that didn’t seem right I put a scope on it and we learned about the pulse modulation being used here.

What extra wire? There are only 2 wires for the signals-ground and hot. The headlight has 3 wires. It is not pulse modulated for bright/dim. Has 2 elements. So ground and a wire for each element.

Here is a link to what the pulses look like: http://cb1100forum.com/forum/showthread....#pid291206
