Can I wire my LED light bar?
You’ll most likely be wiring your LED light bar relay’s power lead directly to the battery, but you won’t necessarily use the same battery’s negative terminal as your ground. You can ground your wiring to the vehicle’s chassis, as long as it offers a clean connection between your circuit and bare metal.
Can you wire 2 LED light bars together?

Do I need a relay to wire a LED light bar?
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 you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
Why do LED light bars have a relay?
Relays can be used to switch a low-current trigger to high current, switch a circuit on or off, reverse polarity, and much more. When adding LED lights, such as off-road light bars, driving/work lights, or other auxiliary lights to a vehicle, you must add a circuit to power the light adequately.

LED Lights with 3 wires will be a multi-function light. They can (most times) be used in whatever configuration is right for your application. For example, running and brake, running and blinker or brake and blinker. These LED’s will usually have a black, red and white wire.
What gauge wire should I use for LED light bar?
LED Lights are expensive and in all cases should be protected against early burnouts. OPT7 Wiring Harnesses achieve this by using silicon infused 14 American Wire Gauge (AWG) cables that better control against voltage spikes and heat.
What size LED light bar?
LED Light Bar. Truck LED Light Bars are available in both Flood and Spot styles and Single or Double row configurations. Light Bars can range from 6 inches to 54 inches in length.
What are interior LED light bars?
Interior LED light bars are specialized to fit within a vehicle as a replacement or supplement to more expensive exterior light bars that mount on the vehicle’s roof. Not only do they cost less than exterior LED light bars but they are easier to mount, are protected from inclement weather conditions and have a higher stealth factor.
What is a LED light bar?
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.
What is a switch harness?
Electronic Switch Harnesses are used to energize the electronic spark module at the proper knob rotation. The switch harness offers a reliable and feasible option when it comes to ignition switches.
