Led taillights light up but don't flash

I just recently put led taillights on my cj. Running lights work, brake lights work, back up lights work even the hazards flash but when you turn the turn signal on it lights up but no flash and I installed an led flasher and still nothing. Any ideas?

I'm thinking......did you have the key on? Simple I know,but, btdt!

It must be a bad connection or something along that line. Other than where generated;hazards,brakes and turn signals share the same line. That's why the key thought........

The LED flasher should have ground wire on it, make sure it's well connected to a good ground.

Yes key was on. And the flasher is just a 2 prong flasher just goes in place of your old one.

You will need a "load equalizer" wired in the stop/turn wiring on each light. LEDs just don't draw enough amperage to "load" the flasher unit to operate. I got a pack of equalizers (2) from Autozone. Wire them in as per the included instructions, and your lights should work correctly.

Hope this helps...

My guess is because he still has front signals that are bulbs. The LED flasher is fine, but the draw the bulbs take makes the flasher think there's a signal that's out. Until the front signals are LEDs, the load isn't balanced. LEDs are kind of "all or nothing" devices.

I have a LED flasher also, ran into the same problems he has. After some research, I installed the load equalizers in the right and left turn signal wire circuit, and the lights work great. Funny thing is, I have a separate flasher for the 4 ways and another flasher for the turn signals. When the 4 ways are operating, there is barely a flicker on the volt gauge. When either turn signal is operating, I have about a 1 volt drop in power every time the flasher is on.

All of my lights work correctly after installing the load equalizers.

Emergency lights on a different flasher than the turn signals?

I have no idea what an "LED" flasher is, but I've had good luck with electronic flashers with LED lights installed. Maybe that's just marketing terminology for an electronic flasher.

I'm pretty sure that his emergency flashers work because the circuit was designed to work with a burned out bulb, where the signal flasher was designed not to so that you will replace the bulb. They designed the "Emergency" flasher circuit to work despite the possibility of damage to the bulbs.

That voltage drop reflects the "equalizers" which are just resistors imitating the resistance of a light bulb.
