LED Tail Lights!

Looking for help with some Led tail lights. Just as a note.
LED headlights
LED tail lights
LED turn signals
Electronic flasher relay for the turn signals.

Here is the issue that I have, when I have the LED headlights off the tail lights function for turning and for braking. When I turn the headlights on, the tail lights stop functioning entirely. I need to know what or where the relay is that needs to be replaced for an electronic one in order for them to work.


Can’t help with that, but some add a load resistor to leds to make them work with stock electronics.
