LED taillights/flashers issues

First off I did a few searches and couldn't find anyone having this exact issue...

I've swapped to all led tail lights and have LED turn signals and high beams up front.
I also replaced my turn/hazard flashers to 12v electronic flashers.

Now I have no turn signals...The signal indicator on the dash is solid. I can tap the flasher and get them to blink once...
And when I try the hazards I get a solid hazard indicator (both turn signal indicators) and a very slow repeated buzzing noise coming from the flasher...

I put stock turn signal thermal flasher back in with an electronic hazard flasher and the hazards work.

Did I get the wrong flashers?

I'm a bit confused on this one.....
Thanks in advance!

Which flashers did you buy? Which bulbs did you buy?

You need no-load flashers.

As for bubs, I find that bulbs marked as "canbus" compatible are also less likely to run into this. Our car's don't have canbus, but bulbs marked as such have an extra resistor across the terminals to increase load to help prevent triggering a canbus equipped car from thinking the bulb is out. For our cars, that extra load coupled with a no-load flasher usually works out fine. This is not the same as the dummy load resistors that some people recommend (skip those). Some people do fine with the cheapest bulbs and no-load flashers. Others have random issues.

I'd start with the flashers. Usually that's the issue.

The bulbs are from super bright leds, and yes I specifically avoided canbus bulbs.

Went to Advanced and picked up two new "name brand" flashers and still no dice...

Frustration beverage incoming...

You just need to get heavy duty flashers. Not because you need heavy duty flashers for LED’s, but because they are specifically designed to always blink at the same rate no matter how much (or how little) load is on them. LED’s draw very little current and this presents a problem for systems designed around terribly inefficient incandescent lighting.

I think you got that backwards. Canbus bulbs are a plus not minus.

They were probably thermal or otherwise not no-load flashers. There are multiple threads on here with examples of no-load flashers that people have tried for LEDs. You can get them from Amazon and ebay.

Success, the cf12anl-01 flashers are the way to go.

Going to do the Tamiya red mod on my lenses and will post pics/vid once they are finished.

Thanks again guys!
