MGB Headlamps: Classic Units, Bulbs and Fitment

An MGB may retain original lighting or have a later conversion. Identify the installed bowl and beam arrangement before selecting a classic replacement.

An MGB headlamp search is usually about keeping a classic car's lighting working while preserving its original appearance, or finding a safe replacement for an earlier conversion. Begin with the lamp currently fitted: note its diameter, retaining rim, bowl arrangement and bulb marking. Restoration history can mean the car no longer carries the equipment it left the factory with.

MGB Headlamps: Classic Units, Bulbs and Fitment

Common questions

Questions before you buy

What size headlamp does an MGB use?

The correct size depends on the headlamp arrangement currently fitted and any modifications. Measure the existing unit and check the car's parts information before choosing a replacement.

Can I fit a Wipac headlamp to an MGB?

A Wipac classic unit may suit some installations, but confirm diameter, bowl and rim fit, wiring, bulb type and UK right-hand-drive beam pattern for your particular car.

Does an MGB headlamp need a UK or European beam pattern?

For UK road use, the beam must be suitable for left-side traffic and must not dazzle oncoming drivers. Check the lamp's stated pattern and applicable approval for the vehicle.

Should I replace the bulb or the complete MGB headlamp?

If the housing, lens and reflector are sound and the light source is replaceable, a bulb may be all that is needed. Corrosion, damage or a sealed unit can call for a complete assembly or specialist assessment.
