2009 Camry LE: my rear brake light doesn't work when braking (fully lit), but it works okay for night-time mode (dimly lit).

This problem is affecting just the right side. The left side is okay for both braking (fully lit) and night-time mode (dimly lit).

Troubleshooting: my deduction led me to believe that my bulb is not burnt out and the wiring harness and fuse are okay because the bulb can be lit during night-time mode, just not when braking. I also think that my brake pedal switch is okay because my left-side brake light is fully lit when braking. I can only speculate it's a circuitry/logic board problem of some sort; I'm just not sure where I can locate the problem.

Has anyone experienced this?

I can't find older posts describing this exact problem, hence starting this thread. Apologies if they do exist. Any help is greatly appreciated. Thanks.

 

Was not aware the brake lights dimmed at night, thought there was only one setting on/off.

If any of the brake lights work the brake switch is working.

You might be mistaking the taillights being turned on. The brake and taillight filaments share a common bulb.
