1979 Honda CB750K · Turn Signal Lamps, Stems, Lenses & Reflectors Buying guide

Check the lamp system before choosing its relay

The three-prong relay is specified for 12V 23W lighting and excludes custom LED lights. The gasket is a separate lamp-service part; reflector hardware serves a different mounting job.

Keep the relay’s lighting restriction visible

This relay’s description gives a 12V 23W specification and explicitly says it is not for custom LED lights. If the motorcycle’s signals have been changed, compare the installed lighting with those requirements before choosing the relay. Model fitment alone does not answer that question.

Order the gasket for the matching lamp

The gasket description identifies its companion lens and signal-lamp listings. Use those references to check the lamp housing you have, especially if its signals were replaced previously. The reflector bolt is a separate hardware purchase with its own individual-unit quantity instruction.

Questions about signal relay, gasket & reflector hardware

Can this relay be used for custom LED signals?

The listing explicitly says this relay is not for custom LED lights. Its stated lighting specification is 12V 23W, so read that restriction before selecting it for a motorcycle with altered signals.

What does the signal gasket listing help me match?

It supplies the Honda reference 33406-431-781 and identifies the companion lens and signal lamps. Compare those product references with the installed assembly; a model-year match alone does not identify an aftermarket lamp.

Is the reflector bolt sold as a pair?

The description says two bolts are used per motorcycle and that they are sold individually. Count the fasteners you need and choose the quantity explicitly rather than assuming one order contains both bolts.

Not sure which part you need?

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