1. You can do some quick electrical tests if you have a multi-meter. Such as testing for:

• Power on the red wire terminal cavity when headlight switch is turned on
• Power on the light green wire terminal cavity with the brake pedal switch depressed
• Continuity to ground on the black wire cavity terminal of the socket.

2. If you don't have a multi-meter, you can still do some other checks.

• First look at the ground wires going to ground G602; refer to this other thread for the location. https://honda-tech.com/forums/honda-...rking-3313363/
• You can also swap the brake light/tail light socket between the driver and passenger side to see if that is the cause.

3. The 3 sockets are for different functions; so, no, there are not 3 different part numbers for the brake/tail light socket. Only 3 different part number for 3 different sockets. Only caveat, is that there may be a part number difference between coupe vs. sedan. Is your car a sedan or coupe? Regardless, the brake/taillight socket Honda part number is 33515-S50-003 for sedan and coupe.

• One socket is for the back-up (reverse) light
• One socket is for turn signal light
• One socket is for brake/taillight
