1971 Honda CB350K3 · Brake Light Switch Buying guide

Match the switch to the rear brake control

The rear stop switch is a separate component from the front brake switch. Its application includes the K3, but altered pedal hardware or wiring makes an on-bike comparison important before ordering.

Parts to consider

Identify the faulty switch first

A brake-light problem should be traced before replacing the rear switch. Check the lamp, connections and front and rear switch operation using the Honda service manual. This replacement addresses the rear-pedal switch; it is not the K3’s distinct front-brake switch.

Allow for changes around the pedal

Rearsets or changed footrest hardware can alter how the rear stop switch is mounted and operated. Compare the existing switch location, connection to the pedal and lead reach before ordering. The original-model application does not establish compatibility with every custom brake-control arrangement.

Buying questions

Will this fix a brake light that fails only with the front lever?

The featured part is the rear brake switch. A fault associated only with the front lever calls for checking that separate circuit and switch. Identify which control fails to operate the lamp before ordering a replacement.

Can I use it with aftermarket rearsets?

Compare the rearset arrangement with the switch mounting, pedal connection and wire reach on your motorcycle. The replacement has K3 application, but custom controls may change the way a rear brake light switch must be supported and operated.

What should I compare on the old switch?

Check the mounting position, connection to the rear brake pedal and lead terminals. Photograph those details before removal. If the wiring or controls differ from the Honda layout, have the replacement’s suitability checked before purchasing.
