ABSTRACT:
To eliminate external high-voltage, for example 25 kV insulated-electrical ables connected to a high-pressure discharge lamp in the reflector--light source--supply circuit combination unit, a plastic housing is fitted against the back surface of the reflector, thus taking up space which is usually available and not otherwise utilized within an automotive vehicle, the housing retaining electrical supply and starting circuitry, including a high-voltage source; the lamp (4, 13) is directly connected to the housing which is sealed by a flexible seal to the reflector, to thereby exclude environmental contamination of the interior of the reflector.
