Abstract

A warning light (10) for external use on an aircraft comprises a high-intensity light output light source (14,20). The light source comprises a plurality of light emitting diodes (40) which are arranged to be pulsed with an overdriving signal (32) to produce a higher than normal intensity flashing light output. The overdriving signal (32) is generated by a pulsed drive circuit (30) in response to timing signals received from a flash pattern box at a rate of between 0.67 Hz to 1.67 Hz.
