turn signals don't work when headlights are on

[trppy7]

i just replaced the tail lights to led oracle and when i have the lights on the daylight or nighttime light. the turning signals won't flash b/c of the lights being on, even the fronts lights won't signals. i have to turn them off just to get the lights to flash but won't work at night b/c i need the lights on of course. i was going to replace either the light switch or the turning switch to see if that's work but wanted to ask if anyone else ran into the same problem.

................Hmmm. This is a new one.

If I had to suspect, you need the LED specific flasher to get them to work together. Thats my guess. I was gonna say the sockets are bad but you said they work with the lights off.

I'd grab an electronic flasher locally from advance or napa, like the Grote 44891, and see if it fixes the problem. I use that in my MJ and it helped with a weird issue I was having with my new led headlights and a very quiet yet new thermo-mechanical flasher.

I would also switch to an electronic flasher just to see if it makes a difference. However there's very mixed results of whether you need them or not with the Oracle tail lights. I have them on my truck and I'm still using the same thermal flashers with no issues and I've heard other people say the same. But there's also quite a few people that say they needed to switch. Seems Oracle may be inconsistent with whether they put resistors in the tail lights or not.

I had a similar issue with the headlights stealing the turn signals and it turned out to be bad front sockets.  I realize this doesn't include the Oracles into the mix, but bad grounds are bad grounds and can do weird things.

X2 on bad grounds. With a dual filament setup you’ll end up with the one circuit grounding through the second filament’s circuit, and then when the second filament gets powered you lose the ground through it. You might also see all the marker lights blinking dimly with the turn signals.

If they worked fine before the Oracles went in I would double check that they’re wired in correctly.

I would also double check whether or not they say the Oracles are fine without an electronic flasher unit. A conventional flasher relay needs load to function, and LEDs aren’t always enough load. If you have a bad ground and it’s blinking the whole marker light circuit with your headlights off it’ll add load to the system, which might be enough to make a conventional flasher behave normally, but then with the headlights on you lose the extra load.

Double check your grounds. A bad ground will cause all sorts of electrical gremlins with headlights and turn signals.

I had some turn signal issues that were worse in very hot weather.  Standard bulbs everywhere.  It turned out my battery was on the way out and when I put in a new battery the signal problems went away.
