One or more layers of LEDs shine light into an array of elliptical reflectors. Each elliptical reflector has an LED at one focal point and shares the second focal point with a larger parabolic reflector that collimates the light. A hole in the center of the parabolic reflector receives additional LEDs, with or without collimation optics.

A lighting assembly apparatus for wingtip position lights and an anti-collision light (ACL). The lighting assembly apparatus reduces light flashback caused by the ACL by including one or more internal baffles located inside of a lens. A lens retainer receives the lens. The lens retainer includes a base section and internal baffles. The one or more internal baffles include a crossbeam baffle that is attached between upper and lower surfaces of the lens retainer. The crossbeam baffle reduces light flashback caused by the ACL and complies with ACL/regulatory requirements. The internal baffle includes a stepped edge that also reduces light flashback caused by the ACL and complies with ACL requirements.
