Brake lights not illuminating when braking (not the bulb)
My passenger outer tail light bulb illuminates normally when the headlights are on, but doesn't illuminate the 2nd filament when brakes are applied.
I have tried swapping with the good bulb from driver side and same result. 3rd brake light works.
Anyone know how/where that bulb/circuit is grounded? Anything else to check? It's an aftermarket tail light housing but has been working fine for years.

There is only one fuse for all the brake light bulbs.
On each light bulb, both filaments (brake and tail) use the same ground.
Remove the light bulb and check for 12 volts on the contact in the socket.
