How do you wire up a LED light bar?

Is a relay needed for 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. To begin with, look at your relay switch and notice the four prongs on it marked 30, 87,85, and 86.

Why does my LED light bar have 3 wires?

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 size wire do I need for a LED light bar?

72 watts @ 12 volts is 6 amps, so I’d probably use a 10 amp fuse. The wire size you need depends on the length of the run. For a run of up to 15′ you could use 14 gauge wire.

What size fuse should I use for LED lights?

75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.

How many amps does my LED light bar draw?

LEDs use about one-fifth the power for the same amount of light output. So for your light bar, it would consume one-fifth of the current, i.e. 0.2 amps from a 120 VAC source, or 2 amps from the car battery.

What is the yellow wire for on LED lights?

The yellow and white on the right is hot and neutral from the source and the black and white on the left are hot and neutral out to your light fixture. I’m not positive though.

Which is the positive wire on an LED?

The voltage supply side of the diode is the positive (+) side, this is called the anode. The negative side is called the cathode.

How do you ground an LED light?

The cable in the wall or ceiling should have a ground wire along with the conductors. If the wall or ceiling electrical box is metal the box should be grounded by attaching the ground wire to the box. If the LED light fixture has a ground wire built into it that should also be connected to the ground wire in the box.

Can you wire light bar into high beams?

The most important thing to remember is that you must wire them in parallel, as opposed to in series, to prevent overloading the existing circuit. If you choose to wire your lights into the existing high-beam circuit, they will only operate when the high beams are on.

How do you wire a Stedi light bar?

Remove your high beam plug from the rear of the headlight and connect it to the piggy back adaptor supplied. The other end of the piggy back adaptor will then connect to the back of your high beam globe. The last end of the adaptor (White T-Connector) will connect to the STEDI Harness.

Can I use 18 gauge wire for LED lights?

Most people would likely recommend using a solid core 18-gauge wire for your LED lights. … This wire size is capable of handling much more than your average system. If you are going to install several 12v LED lighting with dimming options, you might want to grab wiring connectors, which can help you with your wiring.

Can you use speaker wire for LED lights?

Yes you can(with the appropriate current rating being taken into consideration, as discussed elsewhere), but speaker wire is more expensive than normal wire “because of better audio properties”, so why not just get some cheap old regular wire..

What cable is used for LED strips?

You should use 2-core cable, 1.5mm thickness, for your starter-leads. This will allow you to position your LED strips up to 15m away from the transformer. Follow these wiring guidelines, and the brightness of your LED strip lights will be consistent from start to finish.
