Hey all, My classic motor scooter is battery-less and runs 12v AC. I am currently trying to run panel less and wanted some smaller indicators so it's still road legal and bought some LED ones without thinking about it as you do. I then realised afterwards that I need to somehow convert the power, I know very little about electrics and LED's in general. From what I've googled I need to run a converter something like this: www.superbrightleds.com/moreinfo/battery-and-cps-compact-power-supplies/12v-ac-to-dc-converter-module/1725/I'm completely unsure, especially since they're not going to be on constantly. Other threads on the matter make it seem very complicated with different resistors, Ohm and AMP differences. Is there anyone out there that could dumb it down even further? I can measure different readings of power from the scooter using a meter if equations need to be done, cheers.

If it had indicators in the panels you removed, can you refit just the indicators to the bike without the panels? LEDs won't work with ac power (unless you convert it to dc with a black box , rectifier etc) Old-school bulbs work fine with ac power

Just take them off and tape over the switch, problem solved. They aren't required anyway

They aren't required anyway Since the scoot is a 1980 model I think that may actually be an option according to www.legislation.gov.uk/uksi/1989/1796/schedule/7/madeI'll keep looking into rectifiers as I'd prefer to let the good public know where I'm heading With regards to fitting the lights off the panels, there's no way to mount them well unless I cable tie them up somewhere or make brackets which I don't have the means to do and it would look like a proper hack job compared to the slick billet ones I have =)

I've never actually had working indicators fitted to anything other than my rd125lc I took my test on and my cb900, I always took them off everything else. Arm signals, Forcefully riding/ road positioning and if all else fails a boot into a door panel has always surficed. (Although I wouldn't recommend that if you don't have a clear means if exit)

When I took my test, in 1974, even if you had indicators (my bike didn't) you had to use arm signals.

I seem to remember covering this at tech. A simple rectifier circuit can be built with 4 diodes. Something like this;

I couldn't remember what it was called but I did remember what the schematic looked like! lol

I stand corrected and hold my head in shame about giving wrong information To be fair though it's lucky I remembered anything about it as left school 40+ years ago and haven't thought about it since.
