Restore reliable brake light activation with this Rear Stop Light Switch, designed as a direct replacement for several original Honda rear brake switches. This...
These switches have separate warning-light and rear stop-light applications. Match each replacement reference to its own mounting position and connections, then check the diagnosed fault before selecting the part.
The rear brake-light switch replaces references 35350-MG7-405, 35350-425-003 and 35350-MJ0-921. Compare the existing mounting and electrical connection before ordering. A modified pedal or repaired loom requires its own check of how the switch is operated and connected.
Check warning and stop-light circuits
The oil-pressure switch and rear brake-light switch serve separate circuits. Diagnose the warning or lamp fault using the correct service information before buying a replacement. Do not treat a switch replacement as proof that an underlying oil-pressure or wiring problem is resolved. If the oil-pressure warning stays on with the engine running, stop the engine and have actual oil pressure checked before riding.
Ordering questions
Which references identify the rear brake-light switch?
The selected rear-pedal switch lists 35350-MG7-405, 35350-425-003 and 35350-MJ0-921. Compare those references together with the fitted switch and its mounting before ordering.
What if the rear pedal or wiring has been changed?
Compare the actual switch mounting, how the pedal operates it and its electrical connection. A changed pedal assembly or repaired loom should be checked separately from the original model-year application.
Should I replace the oil-pressure switch just because the warning stays on?
Confirm the cause using the correct service checks first. The warning can require investigation beyond the switch; a replacement part alone does not establish that oil pressure is satisfactory.
