Can some one tell me if I can use a "normal" LED bike light with a the 12v supply on my motorcycle. I am not great with the theory of volts etc . Looking at several sites they seem to list a variety of batteries from 3.7 to 15 volts. Is it that LEDs are not too fussy about these things? Don't want to cook a light unit.
My CandBseen light is many times brighter than my CCM's head light and that has 2 55w Halogens , albeit with crap lenses.

The CandBseen lights would dazzle every other road user I imagine and be quite illegal for a road going vehicle that has to pass an MOT.

How old is the motorcycle in question?

I take it you've tried super awesome bulbs like Osram Night Breaker etc and they're not helping much?

Have a look in advrider.com in the gear section, there will be tons of threads

As far as I know, the 'chips' aka drivers that LEDs need are there to supply a constant current to the LED. Because LEDs start cold and get quite hot their resistance varies loads during use, so to get consistent light and avoid damage the current needs regulating.

Therefore I would assume that the chip could handle a range of input voltages and still keep the current constant. However I wouldn't like to guess if your 7.4V lights would handle 12V...

Not road use.
CCM is 02 but standard trail bike lights are ****
. Issue is with the reflector/lamp design not the bulbs. Tried all sorts. Actually I could get them through MOT with clever mounting of 2, one for dip but that's not the need.

Fair enough then. Must be doable, it'll be a case of either finding the right drivers or regulating the voltage from the battery. Hopefully an electrical engineer will chip in soon!
