Let’s face it, the lights on the majority of old bikes aren’t exactly the brightest are they? The light from the old Lucas headlamps are never going to compare to those on modern bikes, especially if your classic motorcycle is still running with 6 volt electrics. But there are some simple things that you can do to ensure that the original lighting is working to its full potential, and also some easy upgrades you can make using LED lamps to improve the lighting whilst limiting the power required.
The following articles include various suggestions and step-by-step guides which are based on my experience with the lights on my 1951 Matchless G3LS motorbike. However, as the lighting systems on the majority of British bikes were fairly standard for quite a few decades, you should hopefully find these articles useful irrespective of what make or model your bike is.
There is also a separate section of this website dedicated to the maintenance of the Lucas dynamo and regulator battery charging system. This covers topics such as general fault finding if your battery doesn’t seem to be receiving charge, testing and diagnosing a Lucas dynamo and upgrading to 12 volt electrics using a modern solid-state electronic regulator, amongst others. This section can be found by clicking here or following the ‘Lucas electrical system’ link below.
Installing LED lighting
Replacing the standard filament bulbs on your classic motorcycle with modern LED lamps offers a number of important advantages. This article looks at:
- What an LED lamp actually is.
- The advantages of LED lighting.
- Which bulbs can be replaced with LED’s.

- Checking the quality of the wiring.
- Installing a headlamp relay.
- The most appropriate type of bulb.
- Selecting the optimum bulb wattage.

- Legal requirements for rear lights.
- Installing a rear brake switch.
- Installing a front brake switch.
- Changing the bulb and LED options.
Lucas electrical system
For specific tips and guides for the Lucas electrical system fitted to many classic bikes there is a separate dedicated section of this website which covers:
- Testing a Lucas dynamo.
- Repolarising (‘flashing’) a dynamo.
- Converting to 12 volt electrics.
- Replacing the regulator and ammeter.
