Scion xB brake lights not working, brake light switch and fuses replaced on Scion xB

Some Scion xB owners report experiencing issues with brake lights that remain non-functional even after replacing the brake light switch and fuses. These problems may stem from burnt-out bulbs, where the new bulbs could be faulty or the bulb socket itself might have issues. Additionally, some owners encounter electrical problems or wiring issues along the circuit that contribute to the malfunction. The brake pedal switch, which is critical for activating the brake lights, may also be improperly adjusted or malfunctioning. Furthermore, some report that the brake lights work correctly when the headlights are off but fail when the headlights are on, indicating a potential wiring issue related to the headlight circuit. If these issues persist, it is advisable for owners to seek a professional mechanic's inspection to accurately diagnose and resolve the brake light system problems.
