Abstract
A flashlight comprising a mercury vapour discharge lamp (12) as e.g. a HID Lamp (High Intensity Discharge Lamp) with adjustable light output is described. The extreme brightness and peak intensity of mercury vapour discharge lamps (12) is enabled for signalling in mobile lighting applications without reducing the lifetime of the 5 mercury vapour discharge lamps (12).
