Abstract
An electric current path for an oscillating warning light of an emergency vehicle includes a spring that is connected between a stationary base of the warning light and an oscillating assembly of the warning light.
Claims21
1) An oscillating light apparatus comprising:
- a stationary base;
- a light assembly mounted on the base for oscillating movements of the light assembly about an axis relative to the base;
- a motive source operatively connected with the light assembly to selectively move the light assembly in oscillating movements about the axis relative to the base;
- an electric circuit operatively connected with the light assembly to selectively supply electric power to the light assembly to illuminate the light assembly;
- and,
- a spring that is part of the electric circuit.

12) An oscillating light apparatus comprising:
- a stationary base;
- a light assembly operatively mounted on the base for oscillating movements of the light assembly relative to the base;
- a spring having a length with opposite first and second ends, the spring first end being operatively connected to the base and being held stationary relative to the base and the spring second end being operatively connected to the light assembly and being held stationary relative to the light assembly whereby the spring second end will move in oscillating movements relative to the base with the light assembly;
- and,
- an electric circuit operatively connected to the spring first and second ends where the spring is a conductor in the electric circuit.
