All the rear lights glow at night and while braking the already glowing lights just glow stronger. Only the additional brake light in the middle works as intended.
In day light all the lower lights also glow while braking. That can’t be correct.
Only two of the four lower rear lights should be brake lights and only 2 should be the regular rear night lights. Well plus the one in the middle of course. Maybe two of them are even the blinkers, I don’t know. But it’s your job to figure out things like that. All I know is, the way it currently is can’t be right.
