Infra-red driving light kit (IR headlamp filters and isolating switch)

Lucas · United Kingdom · 1960–1985

The Series-era night-driving fit: a dash switch that isolates every lamp on the vehicle except the headlamps (no side, tail or brake lights) so that, with infra-red filters clipped over the headlamps, the driver wearing IR goggles sees the road while the vehicle shows only a faint red glow. Reliability problems led to a March 1982 EMER instruction allowing the IR switch to be removed, and active IR gave way to passive image intensifiers.

Part of the MoD 'IR and convoy lighting' specification for GS, CL and FFR Rovers

Rarity. Fitted to FFR and many GS Series and Lightweight vehicles, but the switch was often removed under the 1982 EMER modification after contact burning and the filters were seldom issued; switches and decals survive, complete filter sets are scarce.
