1975 Honda CB550K · Signals & Reflectors Buying guide

Signals that seal

Decide whether you need a lamp gasket, lens screws or a reflector mounting piece. Compare the fitted signal housing and lens fasteners with the listings, especially where replacement or custom signals have already been installed.

Match the fitted signal housing

The gasket and two-screw set list CB550K models from 1975 to 1978. That application does not identify a modified motorcycle’s signal housings. Compare the existing gasket shape and lens screws with the product photos, and check the listed replacement lamp references when necessary.

Check complete lamp availability

Complete signals and several lens colours are listed alongside the gasket and screws. Current publication differs between the US and Canadian storefronts, so check the individual listing before planning a complete lamp replacement. The featured gasket, screws and reflector are published in both.

Common questions

Does the lamp gasket fit the 1975 CB550K?

The gasket listing includes the 1975–78 CB550K and references Honda 33406-377-671. Compare the fitted signal housing and existing gasket shape, particularly if custom or replacement signals have already been installed.

What thread do the reflectors use?

The screw-on reflector listing specifies a 6 mm thread and references Honda 33741-340-670. Its application includes the 1974–78 CB550K; compare the fitted reflector mounting before choosing it.

Is the front reflector rubber base listed for 1975?

The rubber base references Honda 33743-341-670 and lists CB550K models from 1974 to 1976. Compare the base beneath your fitted front reflector with the listing; it is separate from the screw-on reflector.
