1970 Honda CB100K0 Turn Signal Parts

A turn signal housing can outlast its seal, but a replacement lamp may need a different gasket. For the 1970 CB100K0, begin with the fitted assembly and compare the gasket reference before buying a seal for its lens and housing.

1970 Honda CB100K0 · Turn Signal Parts Buying guide

Choose a gasket for the lamp you have

This featured gasket replaces reference 33443-268-671 and includes the 1970–72 CB100K in its application. Its value here is a specific lamp-sealing repair, with the fitted housing determining your final choice.

Match the housing and lens together

A gasket should be chosen for the lamp assembly it must seal. Keep the existing lens and housing identification together when comparing parts. A signal changed during the bike’s life can look suitable from a distance while needing a different sealing shape.

Use the reference to narrow the choice

The replacement reference 33443-268-671 gives you a concrete starting point for matching this gasket. It is listed for the 1970–72 CB100K. If the fitted signal cannot be identified, obtain confirmation of the housing match before ordering rather than assuming every classic Honda lamp uses this seal.

Buying questions

Which matching lamp parts are identified for this gasket?

The product identifies lens 11-2110 and signal lamp 11-2122 as matching components. Use those references to identify an existing assembly; they do not establish that an unmarked aftermarket lamp uses the same sealing shape.

How do I choose a seal for a changed signal housing?

Start with the replacement housing and lens identification. Compare their sealing shape and required gasket reference with 33443-268-671; the motorcycle’s model year alone cannot establish a match for aftermarket lamps.

What information helps confirm an unidentified lamp?

Provide clear views of the housing, lens and gasket seat, together with any markings or part references. These details make a fitment check more useful than a general photograph of the motorcycle.

Not sure which part you need?

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