A motor-vehicle headlight uses a gas-discharge lamp with a power-supply circuit, the lamp being mounted in a mirror. A screening device reduces interfering electromagnetic emissions. The power-supply circuit is in a housing to the rear of the lamp, and the screening device has a conducting material entirely surrounding the housing and able to provide electrical continuity between a screening braid of a power-supply cable arriving at the said housing and screening arrangements which are associated with the mirror. The invention also proposes a gas-discharge lamp incorporating such screening means.
