Reed RelayThin steel contacts that are joined when they become magnetic. The magnetism is created by a small coil, usually in series with a bulb. | |
Reed SwitchThin steel contacts that are joined when they become magnetic. | |
Reference VoltageA voltage value used in an electronic control module that is conducted to a sensor and against which the return voltage is measured in order to determine the signal value. | |
RefinishRepair of an OEM or previously painted substrate. | |
ReflectorBody or surface reflecting rays, particles, objects. Legal requirement on rear of vehicles. | |
RefractionDeflection at a certain angle when light enters obliquely from another medium of different density (light lens). | |
Regenerative brakingA regenerative brake is an energy recovery mechanism that reduces vehicle speed by converting some of its kinetic energy and/or potential energy (due to elevation) into a useful form of energy instead of dissipating it as heat as in a conventional brake. | |
RegulatorAn electronic device for controlling the output voltage from a generator. | |
Regulator TerminalsTerminals on the regulator that connect to, for example, a warning light, field windings, sensing supply and ignition. Some also output signals to the engine management ECU. | |
