ABSTRACT:
An electrical circuit for turn signal, hazard signal, and brake signal lights of an automotive vehicle has 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 is operable to supply relative high steady electrical current to the first and second relay contacts, the contacts of the first relay when in the first configuration conducting the relative high steady electrical current to left rear light and the contacts of the second relay when in the first configuration conducting the relative high steady electrical current to a right rear light. The turn signal switch, when operated, also causes relative 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 relative high current when in the first configuration and supplying the relative high intermittent current to a left front and the left rear lights, when in the second configuration to cause the left front and the left 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 right rear lights to be illuminated in flashing manner. A hazard signal switch is 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.
