Abstract: A tubular resistor assembly for use in electrical circuits for controlling automotive accessories, including a tubular aluminum or other metal substrate having watertight walls and open ends for connection to a fluid-carrying system, a resistor of a predetermined magnitude disposed on the tubular metal substrate. A control circuit, incorporating the resistor, controls the operation of one or more automotive accessory. The assembly may be used to intentionally heat a fluid passing through the tubular substrate, the fluid may be used to carry excess heat away from the resistor, or both. Multiple resistive elements may be included for multiple levels of control of such accessories as headlights, fan assemblies, and the like.
