1978 Honda CB125S5 Lamp & Battery-Box Parts

Separate a lighting repair from a battery-box mounting repair on your 1978 Honda CB125S5. A screw-on reflector, a signal-lamp gasket and a mounting rubber address different locations. Check the assembly being retained before ordering, particularly where lamps or brackets have been changed.

1978 Honda CB125S5 · Lamp & Battery-Box Parts Buying guide

Identify the lamp or mounting point being repaired

The reflector has a threaded attachment, the gasket follows the signal housing and the battery-box rubber fits a support position. Compare each at its own location before combining the parts in one order.

Parts to consider

Keep the lamp seal with its housing

The turn-signal gasket replaces 33443-268-671. Compare the old gasket profile and the sealing surfaces on the housing and lens. If a lamp has been replaced, identify that lamp first; the motorcycle application does not identify the seal needed by a different housing.

Treat the bracket and battery box as separate mounting jobs

The reflector replaces 33741-340-670 and uses a 6 mm screw-on thread. The battery-box rubber replaces 83618-323-000 and is sold individually. Check the reflector bracket and battery-box support separately, then count the matching rubbers required at the box.

Buying questions

Should I replace a complete signal lamp when its seal is worn?

First inspect the retained housing, lens and sealing surfaces. The gasket is offered separately for reference 33443-268-671, allowing a seal-only order when those other parts are serviceable and the gasket profile matches.

How many battery-box rubbers should I buy?

The rubber is sold individually. Inspect each affected support, identify the matching rubber shape and count the pieces being renewed. Keep any bracket damage on the repair list separately from the rubber quantity.

What should I check on a replacement reflector bracket?

Confirm that the bracket accepts a screw-on reflector and compare its thread with the replacement’s stated 6 mm thread. A matching appearance alone does not confirm the attachment, especially with a changed bracket.

Not sure which part you need?

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