1978 Honda CB750K · Headlamp, Bulbs & Parts Buying guide

Choose the headlamp service piece that matches the fitted assembly

A black bucket changes the case, a chrome rim replaces the outer trim, and a plug addresses the wiring connection. These are distinct parts, with their own replacement references and product descriptions.

Replace a housing without assuming a complete assembly

The bucket listing describes a case, while the rim and plug are separate products in the range. Check the pieces already present before ordering. A case replacement is not evidence that a new lamp, wiring connector, rim and every small retainer come in the same purchase.

Compare custom lighting with the installed components

Alternative lamps and custom brackets can leave the motorcycle with a different arrangement from the stock-style headlamp pieces. Read the chosen product’s dimensions, mounting and electrical details against that equipment. Use verified listing details for the replacement, rather than assuming that every lamp described for a CB750 shares the same housing.

Common questions

Does the black case listing describe a complete lamp assembly?

It describes the headlight bucket or case. Lamp assemblies, trim rims and wiring plugs are listed separately. Check the selected product’s actual contents before ordering a case when the repair instead requires a complete headlamp.

How can I identify the plug for the headlight wiring?

The stock-style plug lists Honda 33130-300-003 as its replacement reference. Compare its photo and connector arrangement with the wiring on the motorcycle, allowing for any changes made when a different lamp was fitted.

Should I choose a rim only by its chrome appearance?

No. Compare the rim profile and the assembly holding it, as well as the listing reference numbers. A custom headlamp can have different trim and retention details even when the finished lamp looks similar.

Not sure which part you need?

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