1. An electrical circuit for controlling the operation of first and second lights connected in series between a power supply terminal and a reference potential, said circuit comprising:
- (a) mode selection means coupled to the power supply and having full intensity, zero intensity and low intensity operating modes;
(b) a power control switch connected between the power supply terminal and said first light, said switch being responsive to the placement of said mode selection means in the full intensity and low intensity operating modes to couple said first light to the power supply terminal;
(c) first controlled switch means responsive to the placement of said mode selection means in the full intensity operating mode;
said means being coupled between said first and second lights for connecting said first light to a reference potential when activated by said mode selection means; and
(d) second controlled switch means coupled between said first and second lights and responsive to the placement of said mode selection means in the full intensity operating mode;
said second means coupling said second light to the power supply terminal and concurrently terminating the series connection between first and second lights when activated by said mode selection means.

Abstract
An electrical circuit for controlling the power consumption of high intensity motorcycle lamps which reduces the voltage across the lamps during long periods of operation and enables the lamps to alternate operation between full and reduced intensity. A mode selector switch is coupled to a relay switch for each lamp so as to vary the voltage thereacross as well as to a power control switch for full intensity operation.

7. An electrical circuit for reducing the power consumption of high intensity lamps for use with motorcycles wherein first and second lamps are connected to a common terminal and in series between a power supply terminal and a reference potential, said circuit comprising:
-
(a) mode selection means having an input terminal coupled to the power supply terminal and having full, reduced and zero intensity operating mode with full and reduced intensity output terminals respectively; (b) a power control switch connected between said power supply terminal (half intensity output) and said first lamp, said switch being actuated when said mode selection means is in the full and reduced intensity modes; (c) a first relay switch having first and second switch terminals and a control terminal, said first terminal being connected to the common terminal between said first and second lamps, said second terminal being connected to a reference potential, said control terminal being connected to the full intensity output terminal; and (d) a second relay switch having first, second and third switch terminals and a control terminal, said first terminal being connected to said power control switch, said second terminal being connected to the common terminal between said first and second lamps, said third terminal being connected to said second lamp, said control terminal being connected to the full intensity output terminal, the placement of said mode selection means in the full intensity operating mode closing said first and second relay switches and connecting the second lamp to said power control switch. - View Dependent Claims (8, 9, 10, 11, 12, 13)
