Wiring LED flashers

Wayne in NE · Apr 10, 2020

I?m replacing the two fender mounted flashing lights with LED units. I removed the original flasher unit and replaced it with a flasher unit for LED lights. The description says that this flasher unit will work with up to four lights. I have tried wiring this up several ways, is there something special I need to do? This is a negative ground system. As always I appreciate your responses.

What is it not doing?

You can use a jumper wire in place of the flasher.

Jump from the 12v power to the light wire. The lights should come on, remove the jumper, lights go off.

The flasher is marked X or 49 for power in, L or 49a for load. The LED flasher is just a variable load flasher, which means it doesn't look at the load, it just operates on a timed event regardless of the load.

The led lights are polarity sensitive. If they don't come on, try reversing the wires.

I have learned that some of the flashers for low current lamps need a ground as well as a connection to power. Jim

That's the 3 connector type, yes one is a ground.

I didn't think those were still around, they may be making a comeback.

they make a 50w 6 ohm LED load resistor to stop "hyper flash" on applications of mixed LED and non LED applications

I put a set on my Ford 5000 last year. I ended up running a ground wire to them (I think the ground wire on the lamp was white) as the fender was inadequate. There were two power wires; black was low brightness and red was high brightness. Took some trial and error to get them working but I am happy with the results.
