A method for replacing non-HID landing and taxi lights in an aircraft wing housing that originally was designed to contain the non-HID landing and taxi lights in side-by-side relationship, is accomplished by installing an HID landing light (18), an HID taxi light (20) and an power control device (36) in the space originally designed to accommodate the non-HID landing and taxi lights. A single ballast provides power to both lamps which each comprises a housing (46), an HID bulb (52) supported within the housing, a lens (44) for passage of light from the HID bulb out of the housing, a primary reflector (42) surface disposed behind the HID bulb, and a secondary reflector (68) surface disposed in front of the bulb for reflecting light from the bulb back through the bulb for further forward reflection from the primary reflector surface through the lens. The lens may have a lenticular array (76) including a plurality of cylindrical surface elements (84, 86) for spreading the light beam emitted by the lamp. An HID ignitor (108) may be located within the lamp's housing behind the reflector surface and electrically connected to the HID bulb.
