As soon as you get the awesome idea to run LED lights on your bike to save power you’ll notice your turn signals don’t blink anymore. That’s because they work with the load from the incandescent bulbs, and when you put your LEDs on them, they don’t have enough load to flip the flippyswitch. (Yes. Tech talk, I know, but I have the pertinent licenses, I assure you.)
These guys, Custom Dynamics, have this: the Motorcycle Trick Flasher Relay. They also need to spring for a good product photographer yo.
Thanks to N&V for the tipppytip.
