Abstract
1,222,206. Road traffic signals on vehicles. JOSEPH LUCAS (INDUSTRIES) Ltd. 12 Aug., 1968 [25 Aug., 1967], No. 39247/67. Heading G4Q. In a direction indicator system for a tractortrailer vehicle, having first and second flasher units 15, 16 connected in series between a supply terminal 11 and the movable contact of the direction indicator switch 12, the current flowing when the tractor indicator lamps 17 or 18 only are energized is insufficient to operate the second flasher unit 16, so that the frequency of operation is determined by the first flasher unit 15. The indicator system also has a switch for short-circuiting the first flasher unit 15, and when the tractor and trailer indicator lamps are energized together by engagement of a plug and socket 21 the current flow is sufficient to operate the second flasher unit 16, the flasher units being chosen to provide the desired same frequency of operation irrespective of whether the plug and socket 21 is engaged. The switch for short-circuitng the flasher 15 may be provided by the plug and socket connector 21, as shown, or may be a manually-operable switch on the tractor. Incorrect positioning of this switch is indicated to the driver by a flashing rate which varies substantially from normal. The flasher units 15, 16 may include a metallic vane having a constraining band which ensures that the vane has two stable positions between which it snaps as the band is heated and cooled. A warning lamp 19 indicates when the flasher lamps are operating. The flasher 15 is connected via a fuse 14 and ignition switch 13 to battery 10.
