A portable warning device for a vehicle, preferably an automobile, provides, in use, a reminder to the driver of the vehicle to keep left in a left hand drive country, or vice versa. The warning device is conveniently in the form of a tubular housing (10) with an enlarged plug (11) at one end and an electrical connector (12) at the other end, the housing being arranged to be plugged into a conventional cigarette lighter socket (13) of a vehicle, so that electrical circuitry in the housing is powered, in use, to generate a visual warning by illumination of an arrow (14) on the plug (11) by a bulb. The housing can either be reversibly engageable in the socket or can have its plug (11) rotatable to direct the arrow to the left or to the right as required. In other embodiments the power supply is independent of the vehicle, and the reminder can be a non-verbal, aural warning. The electrical circuitry may be adapted so that the direction indicator (14) is initially illuminated for a predetermined time and then turned off. <IMAGE> |
