However there is no problem simply placing a suitably rated rectifier diode in series with the LED lamps. By suitably rated I mean one that can handle the current. This will simply block the reverse half cycles and protect the LEDs. On the forward half cycles it will pass current and if a low drop type is chosen will not lose to much voltage.

That makes LEDs flicker at 50Hz or 60Hz. It is best to connect two LEDs back-to-back then connect those in series and in series with a current-limiting device. Then the LEDs protect each other and the flicker is at double the frequency which is not as irritating.

Surely this depends upon the bike alternator frequency? This is not mains.

 

Is this the bike thread?

 

To start off I am working on this dirtbike. It's all AC power there's no battery. I'm looking to hook a LED tailight up to it.

I sincerely hope so. Some of the original electrical info is a bit suspect, but I suspect Dustiin is correct about the bike.

 

64 post for motor bike led tail light,could some one do
a drawing of the voltage,flicker and all the other comments
put together in a drawing. I see people wearing battery
operated leds with different color attached to clothes.
They are very bright and last along time on batteries.

 

Well, I believe I have it now. Since I'm going to have to get a regulator, rectifier then connected to a battery to run the LEDs should be a very smooth DC signal. Thanks for everything guys.

 

Good luck, we'll be here if you need anything else.
