led tailight help (already searched)

I have searched the forums and cant find what i am looking for. I installed a set of the led trailer lights on my yj and cant get them to work properly. When i turn the lights on only one tailight lights up and both blinker lights come on on the dash and stay lit. When i hit the brakes they come on fine and the hazards work fine but have no blinker what so ever and only the one running light. I HAVE THE EL 12 FLASHER BUT STILL NOTHING DIFFFERENT. Does anyone have wiring diagram of the tailights. I went by what stu had on his site at stuoffroad because all of the colors were the same but maybe something has changed. I am trying to get everything working properly before tearing down for paint thanks for the help

Double check the connection on the taillight thats not coming on. Unless you have a short in your wires before it gets to your rear end it should work. I twisted wires together till I was certain where everything went, the electric flasher was a headache for me.

You might have a bad electric flasher because my flashers wouldn't blink till I got it cause it wasnt enough voltage to trip the relay? Hope that helps I'm no pro but just going by my mistakes.

the light comes on when i press the brake and when flashers are on. It just turns off as soon as i put the parking lights on and as stated before have no blinkers at all on either light. it is confusing and time consuming thanks for the help

you need to raise the resistance in the circuit to trigger the flasher unit, its a common problem we get over here when people convert US cars to UK lighting regs, you need to find a resistor ( not sure what ohm) and have it connected across the + feed from the lamp and the earth so its wired in paralell.

Check you ground for the light. Oh most of the leds White is the ground.

X's 2 sounds like a ground issue to me. The stock lights are grounded to the tub, if you didn't run a specific ground wire for the new lights they're not grounded.

BTW, the EL-12 (as I'm sure you know) corrects the two issues previously stated about tripping the flasher etc...

i agree check the ground then throw a resistor on em, when i did mine i didn't use em when i would hit my blikers they would blink crazy fast to where u couldnt see them blink just looked like a steady light, got a resistor for each side and problem solved

The best way around the resistance type flasher is to simply replace it with an electronic base flasher. Plug and play.

OP already has the EL-12 flasher.

My opinion is that he has grounding issues, which was already suggested by dodger889, timatoe & T-Mack so I was just keeping my mouth shut on this one.

OOPS!

Well if the grounds are good, then is it possible that the EL-12 was installed in the hazzard slot rather than the turn? Or did you swap out both with the El-12?

Most all of those trailer light pigtails have a 3 wires.

RED = stop, brake, & turn

BLACK = parking lights

WHITE = ground for both bulb circuits

Thanks for all of the input guys, figured out the problem. I guess i moved the wire connector around too much and broke the solder connection but it was under shrink wrap so i couldnt see it. After reattaching everything works great
