FAQ:

Q: What does the dimmer switch do?

A: Headlight dimmers work in a different way. The dimmer switch actually controls two separate circuits. When the normal lights are turned on, the dimmer sends a small current to an electric switch called a relay. This current closes the switch, turning on the normal headlights.

Q: What is dimmer control?

A: Dimmer switches are devices that allow the amount of light a lamp is emitting to be controlled. Whereas a lamp or lighting fixture without a dimmer can only be turned on or off, a light switch with a dimmer can be controlled so the light is set to a desired level of illumination. Grid List.

Q: What is a dimmer switch?
