1980 Honda CB750K · Turn Signal Lamps, Stems, Lenses & Reflectors Buying guide

Separate a lamp sealing repair from a flasher replacement

The gasket has a stated pairing with the DOHC signal lamp range. The relay is a three-prong electrical unit with its own specification, including a restriction against custom LED lights.

Use the gasket’s pairing information

The gasket description pairs it with the amber lens and black or chrome front and rear lamps identified in that product information. Compare your retained housing with those references before ordering. A different signal fitted during a custom build is not identified by the motorcycle’s model year alone.

Read the relay specification before replacing a flasher

This relay lists 12V/23W, three prongs and a rubber mount attached. Its page excludes custom LED lights. Check the fitted lamp arrangement and connector before ordering; selecting a relay by the bike category alone does not establish that it suits a changed lighting system.

Common questions

Does the gasket include a turn signal lamp or lens?

The product is listed as a gasket, with its own reference and pairing information. It does not list a lamp or lens among its contents. Compare the retained housing before selecting it for a sealing repair.

Can the featured relay operate custom LED signals?

Its description explicitly excludes custom LED lights. Compare the lamps and flasher requirements on your bike before choosing a replacement. A relay listed for the model does not establish compatibility with a later LED conversion.

Does a shared DOHC label confirm gasket fit?

Use the specific gasket reference, shape and listed lamp pairings as the comparison. The broad DOHC label is not enough to identify a signal housing fitted from another model or replaced during a previous custom build.
