By the way, on some cars, the brake lights and the turn signal lights are the same filament. This wouldn’t affect anything in repairing them, except ...
... the turn-signal lights operate on both the front of the vehicle and the rear of the vehicle. Normally the brake lights only operate on the rear.
Just make sure ALL the lights work.
On the left rear, the brake light doesn’t work. We replaced the bulb, but it didn’t fix it. The turn signal works if you don’t have the brake on at the same time. The taillight is “dim,” according to my teen help.
