Re: Tail light issues

Did the lights all work before you installed the LEDs? If so the wiring at the lights may be crosssed especially if the leds are joined for tail lights and brake lights. What I mean is, the LEDs for the brakes uses more than the LEDs for the tail lights and you may be seeing brake LEDs and Tail LEDs together when you turn the key on. Does turning on just the parking lights not the head lights make any difference?

recheck your wiring and make sure the ground wire is correct on both lights.

It is strange that turning the key on is what makes the difference. That powers the turn signal circuit but not the brakes or tail lights.
