Abstract
Developments in airfield operational procedures demand, among otherthings, an ability to taxi even the largest aircraft safely from the runway to the unloading area under the worst conditions of visibility.

The paper describes the development of such a fitting based on the use of tungsten halogen lamps and incorporating a new, very compact and efficient optic. Prototype fittings, now undergoing airfield tests, have given, to date, a very satisfactory performance.
