1979 Honda CB400TI Hawk I Brake-Light & Oil Switches

Keep rear brake-light and oil-pressure faults separate when choosing switches for your 1979 Hawk I. One replacement serves the rear brake-light circuit; the other is the engine’s oil-pressure warning switch. Check the affected system before treating an illuminated or unlit lamp as a failed switch.

1979 Honda CB400TI Hawk I · Brake-Light & Oil Switches Buying guide

Trace the warning or rear lamp circuit

These two switches have different jobs and mounting arrangements. Confirm which component needs replacement, then compare its connection and location with the part removed from the motorcycle.

Plan the rear brake-light repair at the rear control

The rear stop switch is listed for this Hawk I application. Compare the switch with the existing rear linkage and wiring connection while checking what has worn or been altered. A replacement switch alone does not establish the condition of the rest of the circuit.

Keep the oil warning’s purpose in view

The oil-pressure switch is the replacement associated with reference 37240-P13-013. A warning requires diagnosis before a part is selected; replacing the switch should not be used to dismiss a possible pressure problem. Follow the model’s service information for the checks and fitting procedure.

Common buying questions

Should I replace the oil switch if the warning stays on?

First establish why the warning is present. It can require investigation of the pressure system or wiring, rather than an immediate switch order. Use the service manual or a qualified mechanic to confirm which repair is needed.

Will this rear switch replace one fitted at the handlebar?

The featured stop switch is for the rear brake-light arrangement. Compare a handlebar-mounted switch by its own application, mounting and connections; sharing a brake-light function does not make the two mounting arrangements interchangeable.

What should I compare if the rear brake control has been modified?

Check the current linkage, switch mounting and wire connections. The standard Hawk I application is a starting point, but a changed control may need a different arrangement. Resolve that match before ordering the standard replacement.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
