How to Wire a Relay for Off-Road LED Lights

LED Light Bar Hookup

Once you have mechanically installed your new LED light bar, it is time to give it a steady supply of electrons so it has a steady supply of night vanquishing power. Learning how to wire and LED light bar correctly ensures reliability and avoids unsafe operating conditions or damage to your vehicle. Please do not skip over this section unless you have a great deal of experience with electrical wiring and components. Your car or truck battery may appear dull and non-threatening, but it is a potentially life-threatening storehouse of led light bar hookup looking for any way out at the speed of macedonian dating sites canada. Always remove the ground terminal clamp first followed by removing the positive side clamp.

This greatly reduces the risk of shorting the battery, which is both exciting and very dangerous. Removing the positive terminal first risks you or a tool coming into contact with any metal connected to the negative terminal, which is most of the car. Many people make the analogy that electrical current through a wire is like water through a hose. Unlike water hoses, however, pushing excessive electrical current through a wire that is too small will melt the insulation or cause a fire.

Fortunately, you already know how much current your LED light bar requires. So, you can easily choose the size of wire led light bar hookup feed it safely. Below is a list of automotive wire sizes and their safe current ratings. The left column is the length of a wire, in feet. The top row led light bar hookup the number of amps applied to the wire.

Choose a column that is equal to or greater than the maximum current draw of your light bar. The intersection between the selected row and column indicates the proper size of wire, in AWG or American Wire Gauge, you should use for the circuit. It never hurts to choose one gauge larger, which means a lower AWG. This provides a greater margin of safety.

When wiring LED light bar relays or switches, fuse all positive side wires such as from the positive battery terminal to the light bar switch. There are three grades of automotive wire: GPT, GXL and TXL. Your local auto parts will have GPT wire but probably not GXL or TXL grades. These grades have a higher temperature range and better resistance to solvents and other chemicals. If you can led light bar hookup them, use them. Your LED led light bar hookup bar probably has an IP67 or higher rating.

Why compromise that with leaky connectors? Look for quality watertight wire connectors in a local marine store. When wiring LED light bar connectors, use crimpers that are specified for them. Good watertight connectors do not need a coating of silicone or electrical tape. If you are so compelled, however, use marine grade silicone and professional quality electrical tape.

Wrap electrical tape snugly over connectors without stretching or it will slowly unravel later. Automotive relays are inexpensive and most handle 40A of current, which is more than enough for even large LED light bars. The relays are switched via a cab switch whose circuit carries less led light bar hookup 1A. Therefore, for a large light bar you can use a smaller cab switch and smaller wire on the switch circuit. If your LED light bar came with a wiring harness and it includes led light bar hookup relay, use it, end of story.

If you have no wiring harness, use a relay if your light bar draws over 5 amps. When directly switching a light bar, use a switch with a minimum 10A rating. The diagram below shows the bottom side of a standard 12VDC automotive relay. The terminals have a led light bar hookup numbering scheme. A fused wire runs between the positive battery terminal to relay terminal Terminal 85 connects to a vehicle ground point. The load eurasian dating of the cab switch goes to terminal Try to keep wire lengths as short as possible.

Route wires along firewalls or the led light bar hookup chassis. Route wire away from high heat areas. Avoid splicing wire when possible. If you have a rooftop LED light bar, run the power wires through a windshield frame channel. Add a dual waterproof connector near the light bar for easy disconnection when the light needs to be removed. Use separate wire colors for different circuits so they are easily identifiable. For instance, red for the wire from the battery to led light bar hookup relay, black for ground wires, yellow for a wire running from a relay to its switch, and so on.

Watch this video on YouTube Conclusion A lot more can be said in regard to how to wire an LED light bar. However, the information in this guide should be enough for the handy person to complete the task. If you have doubts about your ability to deal with wiring, do not hesitate to employ an electrical specialist. Once your LED light bar has been properly wired, you can drive with confidence knowing that your bright, night-splitting LEDs are getting all the power they can consume, reliably and safely.

Wiring LED Light Bar How-To. Safety First, of Course Tip 1: Neutralize the Ultimate Power Source Your car or truck battery may appear dull and non-threatening, but it is a potentially life-threatening storehouse of electrons looking for any way out at the speed of light. Before you start, disconnect the vehicle battery.

Do not take shortcuts. Sizing up Your Wire Many people make the analogy that electrical current through a wire is like water through a hose.
