Description

Restore reliable brake light activation with this Rear Stop Light Switch, designed as a direct replacement for several original Honda rear brake switches. This unit replaces OEM part numbers 35350-MG7-405, 35350-425-003, and 35350-MJ0-921, helping ensure your brake light engages properly when the rear brake pedal is applied.

Over time, rear brake switches can wear out or become unreliable, which may prevent the brake light from activating. Replacing the switch helps maintain proper signaling to other drivers and improves overall riding safety.

Frequently Asked Questions

How many 1979-1982 Honda rear brake-light switches are included?

One switch replacing Honda 35350-MG7-405 is included, enough for one compatible CB750 or CB650.

How should the brake-light switch be adjusted?

Adjust the switch so the rear lamp illuminates early in pedal travel and goes out when the pedal is released. Brake-pedal height and free play must be set separately to Honda specifications.

Can connector shape alone confirm fit?

No. Match OEM 35350-MG7-405, mounting arrangement, spring length and electrical terminals for the exact year and model.
