1976 Honda CB125S3 Signal Gaskets & Reflectors

A cracked lamp gasket and a damaged reflector need different checks on your 1976 Honda CB125S3. Compare the existing signal housing with the replacement gasket, then examine the reflector attachment separately, especially where previous owners have changed lamps or mounting brackets.

1976 Honda CB125S3 · Signal Gaskets & Reflectors Buying guide

Match the lamp seal and reflector attachment

The featured gasket references 33443-268-671; the screw-on reflector has a 6 mm thread. Use those separate details to compare the parts you are replacing without assuming a changed lamp is original.

Use the lamp reference as a starting point

The gasket references 33443-268-671. Compare that reference with your fitted lamp and inspect the gasket outline before choosing a replacement. If a previous owner changed the signal housing, identify that housing first rather than assuming every signal on the motorcycle uses the same seal.

Check reflector mounting separately

The reflector replaces 33741-340-670 and uses a 6 mm screw-on thread. Compare the receiving attachment and clearance around the bracket before ordering. If only one bracket has been replaced, inspect that side independently rather than assuming both sides retain the same fixing.

Buying questions

Will the gasket suit a replacement turn-signal housing?

That depends on the housing fitted. Compare its gasket shape and reference with 33443-268-671 before ordering. A motorcycle application alone does not confirm the seal used by an aftermarket lamp.

Which mounting detail matters when replacing the reflector?

This reflector has a 6 mm screw-on thread. Compare the bracket attachment and replacement reference 33741-340-670; a modified bracket may use a different mount even on the same model.

What should I check when replacing gaskets on several lamps?

Compare each fitted lamp housing and lens before combining the order. Previous repairs may have left different lamp assemblies on the motorcycle; confirm which positions match gasket reference 33443-268-671 rather than assuming every lamp uses the same seal.

Not sure which part you need?

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