ABSTRACT:
A two-stage brake light system (10) for a vehicle equipped with a brake pedal (12). The system (10) includes a power supply (14) such as a battery of an automobile. An improved switch (20) is provided which is responsive to the quantity of depression of the brake pedal (12). This switch (20) serves to energize a warning light (16) when the brake pedal (12) has been depressed by a first selected amount. The switch (20) also energizes a stop light (18) when the brake pedal has been depressed a selected second amount which is greater than the first selected amount. The switch (20) is designed such that it can be readily installed and adjusted to accommodate the particular mechanism to which it is responsive.
