Light Unit
A Lucas sealed headlamp light unit (reflector and lens assembly) for Fastback, Roadster, Interpol, and Interstate headlamp setups.
This is a Lucas headlamp light unit, the sealed reflector-and-lens assembly that sits inside the headlamp shell and does the actual job of throwing light down the road. It shows up in the catalog under the Head Lights figures, including the listings for Fastback, Fastback L.R. Roadster, Interpol, and Interstate variants, so it's tied to those specific configurations rather than being a generic across-the-board part.

The light unit is the piece you pull and swap when the reflector's gone dull, the glass is cracked, or the beam pattern's no good anymore — it's a self-contained unit rather than something you rebuild piece by piece. Given how it's listed across a couple of catalog entries spanning the early '70s, it's worth checking your own headlamp shell and trim ring before ordering to make sure the mounting and connector setup lines up.
If you're not sure whether your bike came through as one of the Fastback, Roadster, Interpol, or Interstate variants named in the parts book, give us a call and we'll help confirm before you order.
