Abstract:
An electrical circuit for turn signal, hazard signal and brake signal lights of an automotive vehicle, said electrical circuit having:first and second relays each having an energizable coil and contacts which are in a first configuration when the coil is not energized and a second configuration when the coil is energized,a brake signal switch operable to supply relatively high steady electrical current to the first and second relay contacts, the contacts of the first relay when in the first configuration conducting the relatively high steady electrical current to a left rear light and the contacts of the second relay when in the first configuration conducting the relatively high steady electrical current to a right rear light, whereby operation of the brake switch, when the coils of the first and second relays are not energized, cause the left and right rear brake lights to be illuminated in a steady manner,a turn signal switch operable to energize the coil of the first relay or the coil of the second relay by relatively low steady electrical current depending on the direction of turn to cause the contacts of the relay concerned to move to the second configuration,said turn signal switch when operated also causing relatively high electrical current to be supplied intermittently to the first and second relay contacts, the contacts of the first relay presenting an open circuit to the intermittent relatively high current when in the first configuration and supplying the relatively high intermittent current to a left front light and the left rear light when in the second configuration to cause the left front and rear lights to be illuminated intermittently in a flashing manner, and the contacts of the second relay presenting an open circuit to the relatively high intermittent current when in the first configuration and supplying the relatively high intermittent current to a right front light and the right rear light when in the second configuration to cause the right front and rear lights to be illuminated in a flashing manner, anda hazard signal switch operable to energize the coils of the first and second relays with relatively low steady electrical current to cause the contacts thereof to move to the second configuration, the hazard switch when operated also causing relatively high electrical current to be supplied intermittently to the first and second relay contacts to cause the left and right front lights and the left and right rear lights to be illuminated in a flashing manner.
