1977 Honda CB550K Turn Signal & Reflector Parts

Turn-signal repairs on the 1977 Honda CB550K may need a lens gasket, screws, rear stay rubbers or a screw-on reflector rather than a complete lamp. Compare the fitted signal housing and mounting pieces first, particularly if a previous owner changed the signals.

1977 Honda CB550K · Turn Signal Lamps, Stems, Lenses & Reflectors Buying guide

Match the signal housing and its mounting pieces

Lamp gaskets and lens screws serve the housing, while the rear rubbers sit under the signal stays. Side reflectors and their bases are separate choices, with different mounting details to compare.

Parts to consider

Order by the part of the lamp being repaired

The signal gasket and two-screw set each identify matching lamp and lens listings. Use those references and the installed housing shape when replacing small parts. A broad motorcycle fitment list does not show that a gasket or screw set will match a custom signal already on the bike.

Distinguish a pack from both sides of the bike

The rear stay rubber pack contains two pieces, and the listing describes two rubbers for each rear signal. Work from the number of stays being repaired rather than assuming one pack covers both signals. Reflector bases and bolts are separately sold pieces, so check their condition and quantity too.

Common buying questions

Is one rear rubber pack enough for both rear signals?

The product is a pack of two and states that each rear signal uses two rubbers. Count the signals and mounting pieces you are replacing, then choose the required packs; the package quantity alone does not mean a full-bike set.

Do the gasket and lens screws suit any replacement signal?

Their descriptions name specific matching signal lamps and a lens. Compare your installed signal with those products before purchasing. A custom or substituted housing needs its own gasket shape and screw comparison rather than a year-only choice.

Is the screw-on reflector a turn-signal lamp?

No. The reflector is a separate stock-type screw-on part with a stated 6 mm thread. Match it to its mounting base; choose signal housing or lens parts for repairs to the electrically operated turn-signal lamp itself.
