FAQ:

Q: What does a light relay do?

A: A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If your light has a very large amp draw at all, you will want to install a relay switch to keep from overheating an ordinary switch, burning up the wires, and thus reducing the amount of electricity getting to your light.

Q: Do LED lights need relays?

A: A relay is not always necessary with led lights because they don’t draw much amperage. And the cheap switches can handle it. With older style lights a relay is a good idea because they draw more amperage.

Q: What is a LED light bar?

A: An LED light bar is a particular type of electrical light fixture. It is characterized as being elongated and having several “bulbs” on it. Using an LED light bar can be a cost-effective light source for home owners, because LED light bars can be attached to each other and have a tendency to function many years after their purchase.
