Aircraft lighting supplier PWI of Wichita has received FAA parts manufacturer approval authorization for its replacement LED entry-door light for King Air 200, B200/250, 300, and B300/350 turboprop twins. King Air 90-series airplanes are not equipped with an entry-door light.

Mounted between the engine and the fuselage on the left wing, the entry light turns on upon the lowering of the passenger cabin door, illuminating the ground beneath it. PWI’s LED light is a form-fit, no modification replacement for the conventional incandescent bulbs MS24513-4174, A4174-24, and M6363/3-1. The LED light provides a service life of 100,000 hours compared with a 300-hour lifespan for the incandescent bulb, along with a fraction of its power draw. It also provides 730 lumens, compared to 650 lumens with the original bulb.
