Choosing Lucas Electrical Parts for Your Classic Motorcycle
A familiar Lucas part number is a useful starting point, but the correct replacement also depends on your motorcycle’s model, production year and existing electrical equipment. Your parts book, wiring diagram and the specifications in the individual product listing should guide the purchase.
Our Lucas Electrical selection covers several distinct systems, from conventional points ignition and period-style lighting to replacement wiring harnesses and modern combined regulator/rectifier modules. This makes it possible to shop for restoration components and selected electrical updates in one collection while checking the requirements of each component separately.
Lucas Wiring Harnesses and Electrical Connections
A replacement wiring harness needs to match the motorcycle’s equipment and circuit layout. Our selection includes model- and year-specific Lucas harnesses for Triumph twins, Norton Commando models and other classic British applications. Some listings are main harnesses, while others are headlight harnesses or kits supplied with additional components.
Before ordering, compare:
- Motorcycle make, model and production year.
- Original harness number and any listed replacement numbers.
- Main-harness versus headlight-harness coverage.
- Standard ignition versus a harness specifically described for electronic ignition.
- Included components, connectors and installation information.
Browse our wiring harness collection to compare available options. Our article on Lucas and alternative British motorcycle wiring harnesses also explains why a shared application or original part number does not necessarily mean two harnesses have identical construction or contents. Check current product descriptions for the final specification.
Lucas Ignition Parts
The Lucas Electrical collection includes ignition coils, contact-breaker points, condensers, distributor caps, spark plug caps and selected magneto-related components. It also includes both 6-volt and 12-volt coil listings, so the voltage shown in the product description is an important distinction rather than a detail to overlook.
Match the replacement to the ignition system actually fitted to the motorcycle. A points-ignition component, distributor part and electronic-ignition conversion component serve different purposes. Do not assume that every Lucas ignition part fits every Triumph, Norton or BSA.
For a broader view of available suppliers and alternatives, explore our classic British motorcycle supplier brands.
Lucas Alternators and Charging-System Parts
Our selection includes alternator stators, rotors, stator-and-rotor kits and combined regulator/rectifier modules. Listings distinguish between single-phase, three-phase and energy-transfer components, including RM24 stators and RM15/RM19-type energy-transfer replacements.
Check the charging-system type and the requirements of every component involved before purchasing. For example, a regulator/rectifier explicitly described as a three-phase unit should be evaluated against the alternator configuration fitted to the motorcycle—not selected merely because the listing mentions the correct motorcycle brand.
Use the individual product specifications and the relevant installation instructions to confirm compatibility. Avoid treating a charging-system upgrade as a universal bolt-on replacement.
Lucas Headlights, Taillights and Bulbs
Lucas lighting parts in this collection include headlight shells and rims, bulb holders, incandescent and LED bulbs, warning lights, turn signals, taillight assemblies and replacement lenses. The range includes familiar Lucas lamp families such as L564 and L917, but the assembly, lens and bulb requirements must still be checked individually.
When selecting lighting parts, compare the listed:
- Operating voltage.
- Bulb base and holder.
- Wattage or LED specifications.
- Headlight diameter and shell configuration.
- Lamp type, mounting arrangement and application.
- Polarity requirements where specified.
For example, the Genuine Lucas 312 headlamp bulb is described as a 6-volt, 30/24-watt bulb with a British pre-focus base. Those specifications are more useful for identifying the correct replacement than the word “Lucas” alone.
Lucas Switches, Controls and Instruments
Our Lucas range includes ignition and lighting switches, brake-light switches, handlebar-switch repair kits, warning lights, ammeters and horn-related components. Switch families represented in the listings include 88SA, 149SA and 47SA types.
Compare the complete switch description, part number and application before ordering. A switch body, socket, key, bezel and repair kit are different items; purchasing one does not necessarily provide the complete assembly.
Genuine Lucas, Lucas-Type and New-Old-Stock Parts
Product descriptions matter when choosing restoration parts. This collection includes items explicitly described as Genuine Lucas alongside items described as Lucas-type or replica, plus selected new-old-stock listings. Read the individual listing rather than assuming that every item displayed in the collection has the same brand status.
The Lucas Classic website explains the brand’s approach to replacement classic components, including reproductions made from original tooling or replicas of earlier products. That brand background does not establish that every component on a retailer’s page is original-period stock or manufactured in the same country.

Lucas Electrical FAQ
What Lucas electrical parts does The Bonneville Shop sell?
Our Lucas Electrical collection includes wiring harnesses, ignition coils, points, condensers, switches, lighting parts, alternator stators and rotors, regulator/rectifiers, ammeters and selected magneto-related components. Browse the product grid for the current selection and check each listing for its application and specifications.
Which motorcycles can use Lucas electrical parts?
Lucas electrical equipment was fitted to many classic British motorcycles. Our collection focuses on parts with listed Triumph, Norton and BSA applications, with some products also identifying other makes. Compatibility depends on the specific part, motorcycle model, year and electrical system—not simply the manufacturer of the motorcycle.
Are all products on this page Genuine Lucas?
No. The collection contains products explicitly described as Genuine Lucas as well as selected Lucas-type and replica items. Read the product title and description to confirm how the individual item is identified before ordering.
Are new Genuine Lucas parts the same as new-old-stock parts?
No. A newly manufactured Genuine Lucas replacement is not the same as a part identified as new old stock. Our listings distinguish selected NOS items from other replacement products. Use the individual description to determine what is being offered.
How do I choose the correct Lucas wiring harness?
Start with your motorcycle’s model, year and original harness number. Then compare the listing’s equipment requirements and contents, including whether it is a main harness, headlight harness, standard-ignition harness or a version intended for electronic ignition. Visit our wiring harness collection to compare options.
Does a Lucas wiring harness include every electrical component I need?
Do not assume that it does. A harness listing and a harness kit can have different contents. Our collection includes individual harnesses and kits specifically described as including a regulator/rectifier module. Check the included-parts information in the listing before purchasing additional components.
Does The Bonneville Shop offer Lucas harnesses for electronic ignition?
Yes. The collection includes Triumph harness listings specifically described for electronic ignition, including versions for 1967, 1968 and 1969–1970 applications. Check the individual product description against your motorcycle and ignition equipment; these are not universal harnesses.
What is the difference between single-phase, three-phase and energy-transfer Lucas charging parts?
These labels identify different electrical-system configurations, not interchangeable versions of one component. Our collection includes parts identified as single-phase, three-phase and energy-transfer equipment. Match the replacement to the system described in the product listing and the motorcycle’s wiring and installation documentation.
Does The Bonneville Shop sell Lucas regulator/rectifiers?
Yes. The collection includes combined regulator/rectifier modules, including a unit explicitly described for three-phase charging systems and a MOSFET module. Read the selected unit’s specifications and installation requirements before deciding whether it suits your motorcycle.
How do I choose the correct Lucas headlight or taillight bulb?
Match the listed voltage, bulb base, wattage and lamp application. For an LED replacement, also check any stated polarity and operating-voltage requirements. Our collection contains both 6-volt and 12-volt bulbs, different bulb bases, and selected LED replacements, so appearance alone is not a reliable way to choose.
Can I buy replacement Lucas taillight lenses and switch repair parts separately?
Yes. The collection includes replacement taillight lenses, selected lens screws, switch sockets, ignition barrels and keys, and handlebar-switch repair kits. Match the replacement to the specific lamp or switch type identified in the listing.
Where can I learn more about Lucas parts or get help identifying a replacement?
Read the official Lucas Classic motorcycle information for brand background, browse our wiring harness guide for harness comparisons, or contact The Bonneville Shop at orders@thebonnevilleshop.com. Include your motorcycle model, year and any available part numbers when asking about a replacement.
