First Claim
Patent Images
1. Blackout lighting for vehicles operating in wartime conditions, comprising:
- (a.) a first pair of light emitting diodes connected in parallel,(b.) a second pair of light emitting diodes connected in parallel,(c.) a blocking diode,(d.) a blackout marker operator-operable switch mounted accessible to the vehicle operator, having a first terminal connected with the vehicle battery and a second terminal, the switch being operable between a closed-circuit position and an open-circuit position,(e.) a first resistance,(f.) a series electrical circuit comprising the first and second pairs of light emitting diodes, the blocking diode, and the first resistance, to a ground,(g.) means connecting the second terminal of said blackout marker switch with the aforesaid series circuit.

Abstract
Four red light emitting diodes are embedded in a synthetic resin encapsul. Two diodes in each of two pairs are connected in parallel and the two pairs are connected in series with a resistance, a blocking diode, and an on-off switch. A fifth diode which emits yellow light when energized is connected in series with a resistance, a blocking diode, and a brake-actuated switch.
