An aircraft forward position lighting device (1) has a modular configuration, including a mounting module (20) containing solid-state light sources, e.g., light-emitting diodes (LEDs) (210, 230). The mounting module also includes reflectors (220). The pattern of light emanating from the light sources and reflectors satisfy Federal Aviation Regulations (FARs) regarding minimum light intensity. The device includes a cut-off shield module (10) configured to provide angular cut-offs to the pattern of light, so that the device satisfies FARs regarding overlap between position lights. The device may also include a base assembly module (30) that contains electronic circuitry connecting the light sources to a power source in the aircraft. Electronic updates may be performed by replacing the base assembly module. |
