1981 Honda CB750K Turn-Signal Gaskets & Flasher Relays

For the 1981 CB750K, the featured signal service choices are a gasket for the listed lamp family and a three-prong flasher relay. Compare the fitted housing and electrical setup independently. The relay description explicitly excludes custom LED lights, so changed signals need particular attention.

1981 Honda CB750K · Turn Signal Lamps, Stems, Lenses & Reflectors Buying guide

Match the lamp gasket and flasher to different parts of the repair

A gasket replacement deals with the signal housing; the flasher is a separate electrical component. Their descriptions identify the applicable lamp family and relay specification, so neither choice should be made from appearance alone.

Identify the lamp family for a gasket repair

The gasket listing names its matching lens and front/rear signal family and gives Honda 33406-431-781 as the replacement reference. Compare that gasket with the installed housing. Custom signal replacements may use a different seal, so the motorcycle’s year alone does not identify every lamp now fitted.

Check changed signal equipment before ordering the relay

The selected flasher is described as a three-prong 12V/23W unit with its rubber mount. Its description says it is not for custom LED lights. Confirm the actual lamp equipment and relay connections before buying; do not carry the stock-type relay choice into a modified LED setup by assumption.

Common questions

Does the selected flasher listing support custom LED signals?

No. Its description expressly excludes custom LED lights. Compare the equipment now fitted to the motorcycle with the relay specification before purchasing, especially if an earlier owner changed the original signal lamps.

What mount is described with the flasher relay?

The relay description says its rubber mount is attached and identifies a three-prong connection. Compare that arrangement with the relay and mount already fitted; the gasket listing covers a different component and has separate contents.

Can I use the gasket with every aftermarket signal housing?

The gasket description identifies a particular companion lamp and lens family. It does not establish universal aftermarket-housing fitment. Compare the outline and listed replacement reference with the actual signal fitted before choosing the service part.

Not sure which part you need?

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