LED taillight bulb symptoms are odd

[ryanw]

A question for the ones with LED experience. I put LED bulbs in my tail lights only. All other bulbs are stock and I have a electronic flasher so I havent had an issue with flashing. I did my best to get good grounds with dedicated ground wires from the light housings to the body. They work great EXCEPT for when the turn signals are activated, the other rear bulb flashes but it lights up partially like its in "marker" mode. The license plate light also blinks with the turn signal. Any Ideas would be greatly Appreciated! Ive been beating myself up about this....
