LED Tail Lights

I installed VLEDs LEDs in my 2013 CrewMax Tundra. Recently, I noticed an issue with the tail lights. Whenever the the headlights or parking lights are on, and I turn on either turn signal, the tail light goes dim/bright with the turn signal. This happens with each individual turn signal on(only on the side with the signal activated) and with the emergency flashers on.

I have chatted with VLEDs for hours on this and we cannot figure out what is going on and they say they have never seen it before. I replaced the flasher relay last week and that did not fix the issue.

The issue happens with stock bulbs installed as well as the LEDS. If i unplug the resistors, then the issue goes away with the emergency flashers activated, but then I have the hyper flash issue with the turn signals

If anyone has any issues or suggestions or has seen this before, I would greatly appreciate any suggestions or ideas.

Thanks!

which resistor mod did you do.
or the one where you add resistors to each led so they are supposed to act as if they are the right resistance bulbs...
or this one

adding resistors inline with the led would drop the voltage and limit current making the led with the resistors dimmer...
now if your talking about headlights dimming with flashers then something is drawing more amps than it should. I would try my above fixes for hyper flash and see if that fixes both issues likely one or more of the resistors is drawing extra amps could find out which one as the excess amps should be putting out as heat...

Thank you for your response, this is not a hyper flash issue. The tail lights go bright and dim opposite of the turn signal when they are activated. The resistors were sold by the same company that produces the LED bulbs and plug directly into a plug on the wiring for the LED bulbs. The 2 resistors I used are plugged into the wiring of the LED turn signals in the back of the truck.

Anyone know of a way to upload a video to these posts?
