If your spotlight did not come with an electrical relay, you will need to install one. Most stoplights should not be wired directly to a power source without being run through a relay. Purchase a single pole single throw relay from your local hardware store if your kit did not come with one.
This relay will allow you to control the light from the inside of your vehicle. If you are using an aftermarket headlight switch, make sure that the switch is wired in the correct direction. For example, if your headlights are wired to the left side of the vehicle, your switch should be on the right side.

Do you need a relay for LED headlights?
Unlike standard xenon or halogen bulbs that can be used on a plug-and-play basis, LEDs require additional components such as a relay or a switch to turn them on and off. LEDs are also more energy-efficient than incandescent bulbs because they use less electricity to produce the same amount of light.
They also last longer than traditional bulbs due to the fact that they don’t need to be replaced every few years. LED bulbs also emit less heat, which means they are less likely to catch on fire.
Do I need a relay for off road lights?
Only use for off road lights when you are using LED’s with high current draw that need higher voltage levels than what is available to them from the battery in your car. Because of how much power their running at, they will not overheating as quickly. A relay is a device that turns on or off a circuit.
A switch, on the other hand, is used to turn on and off multiple circuits at the same time. For example, if you have two switches, one on each side of your garage door, and you want to open and close both of them at once, you can do that by turning on one switch and then turning off the second switch. Relays and switches can be used together, but they are not interchangeable.
Can you hook up a light bar without a relay?
Unless you have power requirements, you can wire the light bar without Relay, and it will work fine. If the wires are shorted or something is wrong with them, they won’t work, and may cause a fire, it’s important to take care when wiring them.
If you don’t have a power supply, then you will need to use a relay to turn the lights on and off. You can buy relays from any electronics store, but they are expensive.
How many amps before you need a relay?
You will often see circuits carrying less than 20 Amp switched directly, while circuits of 30-40 Amp can sometimes be directly switched, but will usually be controlled by relays. Anything above 40 amps is usually handled by a relay. The most common type of relay is a push-pull type, which is used to control the flow of current through a circuit.
Can you put LED bulbs in stock headlights?
LED headlight conversion kits are only designed to work with stock halogen bulbs. If you want to use a different type of bulb, you will need to purchase a replacement bulb.
Can you wire LED light bar directly to battery?
If you can connect the bar directly to the cables, you can also connect it to the battery. The best way to avoid this is to make sure you have a good ground connection between the bar and the car’s battery, and to use a ground strap to connect it to your vehicle’s ground. This way you won’t have to worry about short circuits in your car.
Why do you need a relay for LED light bar?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a light bulb. A relay can be used to turn on or off a lamp, light switch, or other electrical device.
The term “relay” is often used in the context of electrical switches, but it can also refer to any device that can control the flow of electricity through a circuit. For example, a relay could be a switch on a car that turns the engine off when the car is in motion, and on when it is stationary.
