An oil-warning issue and a rear brake-light fault need different checks on the 1982 CB650SC. Identify the affected circuit before ordering a switch. Compare its reference, mounting and connections with the fitted parts, especially where the motorcycle has modified controls or previous wiring repairs.

The oil-pressure switch references 37240-P13-013. The rear stop-light switch serves the pedal-operated brake circuit. Neither selection replaces diagnosis of the wiring or the underlying mechanical condition that triggers the circuit.
Distinguish a warning-circuit fault from low oil pressure
The oil switch is an electrical component. Its replacement does not establish that the engine’s lubrication condition is correct. Use the appropriate service tests to identify the cause of an oil warning before assuming a new switch resolves the underlying issue. If the oil-pressure warning stays on with the engine running, stop the engine and have actual oil pressure checked before riding.
Check the rear switch at the pedal system
The rear stop-light product explicitly includes the 1982 Nighthawk. Compare its mounting, connection and operating arrangement on the motorcycle. Follow the correct adjustment and function-check procedure after repair, particularly where a custom pedal or linkage affects switch operation.
Oil & Brake-Light Switches questions
Does an oil warning confirm the switch is faulty?
No. Check the warning circuit and actual lubrication condition using the proper service procedure. A switch purchase should follow that diagnosis rather than be used to dismiss the warning.
What should I verify with modified rear controls?
Compare the rear switch’s mount and how the pedal or linkage operates it. The original model application does not establish the correct arrangement for every custom control conversion.
Can I select either switch by connector appearance?
Match the circuit, reference and mounting as well as the connections. A similar-looking electrical fitting is not sufficient evidence that it serves the required function.
