problem with led lights on my comanche

[88elimnator]

ok so the turn signals worked fine then i installed led tail lights and now the turn signal is very very slow to blink when the lights are off, but don't work at all when lights are on. Does anyone know anything about this? Its driving me nuts, thank you

Not to be a crotchety old coot, but if you did those "LED replacement bulbs" get rid of them. I've noticed that they do not cast light against the inside of the lens the same, and are barely visible save for a small point that the light up.

 

They are playing with the delay because they don't draw as much as a normal bulb.

 

But please, if its just the bulb upgrade lose them.

There not the bulb replacements, I kept breaking the stock tail lights so i wrapped the tail light hole with a small sheet of stainless and put in the oval trailer lights, cause they are cheaper and easier to find.

So is there a relay I can get to fix this problem?

There is no relay. But the standard blinker "can" is load sensitive. They are made that way so the blink rate will change if one bulb burns out. However, since LED lights don't draw nearly as much as incandescent lights, they don't activate the blinker.

 

I believe the cure is to buy one of the electronic blinker modules that is NON-load sensing (the kind used for vehicles with a trailer tow package). The blink rate for those is the same regardless of how many bulbs (and thus how much draw) are in the circuit.

I'll try it. thanks

Same issue when we converted to LED tails on our '89 XJ.

 

You'll need to get a electronic flasher. From AutoZone part number EL12 (2 prong) works fine in our application and corrected the issue. Make sure you look to see what flasher you have (2 prong or 3 prong).

An electronic flasher (also called a heavy duty flasher) is one way to solve it, and the simplest. Another way is to wire load resistors in parallel with the turn signals.
