1973 Honda CB500K Headlight Assemblies & Enclosure Parts

A headlight repair on a 1973 Honda CB500K may need a complete assembly or only its enclosure parts. Compare the working lamp, bucket, rim and wiring before ordering. The assembly, empty shell and chrome rim have different contents, and small electrical or adjusting parts remain separate choices.

1973 Honda CB500K · Headlights Buying guide

Compare the complete assembly with parts you can retain

The stock-style assembly includes the light unit and surrounding components. The bucket-only and rim-only choices let you replace narrower damaged pieces, provided the retained parts match. Check the current headlight rather than assuming every round lamp uses the same enclosure.

Parts to consider

Honda CB750 / CB550 / CB500 / CB450 Stock Type Headlight Assembly ~ Replaces 33100-341-701 Stock-style complete headlight assemblyIncludes a 7-inch halogen unit, rim and retainer, plastic bucket, cables and hardware. The CB500K 1971–73 application states that installation hardware is included.View part Honda CB750 / CB550 / CB500 / CB450 Stock Type Headlight Assembly Bucket / Case ~ Replaces 61301-300-020B Bucket-only enclosure replacementThe black shell references Honda 61301-300-020B. It excludes the lamp, rim, wiring and mounting hardware, which must be retained or selected separately.View part Honda CB Headlight Assembly Rim ~ Replaces 33101-300-673 Chrome headlight rim replacementOne rim references Honda 33101-300-673 and 33101-405-671.

Choose the breadth of repair from the actual damage

A complete assembly supplies more components than the bucket or rim. Check whether the existing lamp still works and whether its retaining pieces are serviceable. For a partial repair, match the references and adjoining parts before ordering; a similar diameter alone does not identify the correct rim or shell.

Inspect the connector and adjuster while the lamp is open

A replacement plug repairs the bulb connection, while the screw-and-spring set serves beam adjustment. Those functions are separate from replacing the enclosure. Compare the fitted wiring and adjuster with their listings so a good-looking shell does not leave a damaged connection or missing adjustment component unresolved.

Headlights FAQs

What should I expect in the complete assembly?

The listed components include a 7-inch halogen unit, rim and retainer, plastic bucket, cables, nuts and general hardware. The stated CB500K application includes installation hardware. Compare those contents with the existing components before choosing a complete rather than partial repair.

What fit details matter for a bucket-only repair?

For shell 61301-300-020B, compare mounting width, side-bolt size, rim retention and wiring openings. Inspect the lamp, rim and supporting pieces you intend to reuse; the shell listing supplies neither those components nor the mounting hardware.

Which references identify the headlight beam-adjuster set?

The set supplies one screw replacing Honda 33103-346-670 and one spring replacing 33107-300-003 for one adjuster position. Match those beam-adjusting components to the fitted lamp before ordering; the shell’s main mounting hardware is a separate requirement.
