2018 Mitsubishi outlander ES. Bought this car used and the driver tail light and neither brake lights work. Figured it just needed bulbs but since they are LED i ordered and equipped both new tail lights. Same issue. Went through replacing fuses and relays that had anything to do with lighting and still same issue. Read online that the tag lights or glove box light may be the issue so replaced those. Glove box light now works but neither tag lights work still. The blinkers on both sides work and they are in the same tail light assembly but different connectors. When you first turn your lights on, the drivers tail light flashes but only for like 1/10th of a second. Had to test it multiple times to be sure I even saw it.

We replaced the bulb, also when we put the turn signals on the flasher blink inside the car. The lights to light up the dashboard went out. We checked the fuses they are good.
