Before wiring your off-road lights to your high beams, make sure you have all the materials. Necessary tools include tape, wire cutters, connectors, and a wiring harness. Check that your off-road lights are working and know where they’ll be mounted. Once these steps are done, you can go ahead and wire them to your high beams.

Gather the necessary materials

Necessary Tools for Wiring

To wire them, you’ll need some things. Wiring – 12 AWG or thicker according to wattage. Pliers or another tool to strip and manipulate the wires. Wire cutters, electrical tape, and butt connectors for thicker gauges. Plus, zip ties to tuck away the wiring.

Be aware of state laws on what lights can be used and how. Before proceeding, make sure you know these laws.

Read the instructions for the lights

Before wiring them to your vehicle’s high beams, read the instructions. Make sure to check the wattage and voltage of each light. This helps prevent damage to your car’s electrical system.

Plan your route, and make sure it’s safe. Keep things neat and organized when routing wires. Cut longer lengths than needed. Secure connections away from heat sources with tie wraps.

Pay extra attention in wet areas. Moisture can corrode connections quickly here.

Lastly, use properly shielded wires. These can create interference with vital electronic systems. Use wires designed for such applications if needed or required by local codes.

Mount the Lights

Mount the Lights

First, check you have the right lights, switches, connectors, and wiring. Next, start the mounting process. Attach the lights to each side of the car. Pick a secure place for them – make sure they don’t get in the way of anything else.

Determine the best location for the lights

Decide what type of lights you want to add to your vehicle. Place them on the front so that they light the area with minimal light spillover. Make sure the lights don’t exceed legal height or width limits.

Have at least four mounting points for each set of lights. Include all wiring and hardware before installation. The mounting points can be holes, or clamps – depending on what’s available. Secure each light in its location.

As a safety precaution, check that all metal surfaces are clean and free of rust before attaching any components. This prevents corrosion and ensures a secure connection.

Secure the lights on the vehicle

Secure the lights to the vehicle exactly where you want them. Make sure all mounting hardware is connected securely.

All wiring must have enough gauge to supply the right current load from the battery to each light. This is especially important for multiple lights. If the wire is too small, it can cause failing relays and fuses, which means the lights won’t turn on.

Connect the Lights to the High Beams

Connect lights with high Beam

For a better view when driving Jin the dark, connecting them to the high beam switch is the way to go. So, let’s get started!

Connect the power wire to the high-beam switch

Connecting power for off-road lights is easy, but you must be careful. No matter how many lights you have, it needs to go to the high-beam circuit.

Find the headlight switch and locate the two wires. The low-beam wire is not necessary. The black one should attach to the positive terminal (12 VDC) of your new lights. Then, connect it to the high beam circuit.

Consult your car’s wiring diagram for extra details. Usually, just put the power wire from the lights in an empty slot in the switch connector. Test it with a voltage meter first.

Secure the wires and connection points with electrical tape. Cover up any exposed wiring with a sheath or protective cover designed for cars. This will protect against heat or other road hazards that could damage the wires and connectors.

Connect the ground wire to the vehicle’s frame

It’s essential to attach the ground wire from the off-road lights securely to the vehicle’s frame. This stops any electric shock if there’s not a proper bond. The most straightforward way is to run a separate ground wire from each light and join it directly to an unpainted, rust-free part of the frame. You may need to use a grounding plate where each ground wire links to make the connection perfect.

Connect the switch wire to the high-beam switch

Connect a switch wire from the battery-positive terminal to the “on” position of the switch. This will ensure that when switched off, it uses minimal current. Then, connect the other terminal of each light’s switch wire to its positive terminal or power lead (usually red).

Next, connect one end of another wire (preferably thicker) from each light’s negative terminal or ground lead (usually black), towards the headlights and hook it into its high beam switch. Double-check all wiring connections for any issues before testing out lighting functions in outdoor and indoor conditions.

Test the Lights

High Beams Testing

Before wiring them, test them! Ensure they work, are mounted right, and output the correct amount of light. Understand how the light setup works first.

Let’s review how to test them properly:

Check all connections for tightness

Check all connections for tightness before connecting your off-road lights to the vehicle’s high beams. This includes side terminal wire connectors on the fuse block or relay and crimped spade or ring terminals connecting wires to switches and lights. Loose wires can cause arcing and generate heat. This can melt the insulation and cause a fire, so it is best practice to use electrical grease when making any electrical connection.

To make sure the wiring is connected properly, use a voltage tester. If all wiring is in order, you will get power back from any hot leads tested with the tool.

Turn on the high beams and check that the lights work

Turn on your high beams to easily identify the correct wiring and make sure all the connections are secure. Test the lights to make sure they are functioning properly. Inspect the ground-side wires connected to off-road lights and check for any loose connections or other damage.

Test each individual light by turning it on and making sure it responds when receiving a signal from the high beam. Adjust the headlight switch between low and high beams to see if each light responds to different levels of illumination. Replace any broken wires or bad connections before closing up.

Now you’re ready to hit the road, safe in the knowledge that your off-road lighting system won’t let you down!

Final Touches

Wired the lights? Ok! The last bits need to be done. Turn the switch on and off, connect the power wire to the battery, and make sure the lights turn on when using the high beam.

Let’s have a look at each one in detail.

Secure any loose wires

Finally, it’s time to secure any loose wires. Use rigid zip ties for a grip. Or, use metal clips for a tighter grip and easy removal if access is needed again. Keep the wiring neat to avoid accidents. Once all wires are secured, snap covers back into place to complete the installation.

Test the lights one more time

Turn the car’s engine on and switch the ignition to “on.”

Test the relay by switching from low beam to high beam. Check that the wires are connected correctly and all connections are secure.

Turn on the high beam and flick each light switch one at a time to make sure each off-road light is lit. Once each light is lit, press both switches at once and check they all work together. Test dimming too.

Adjust any headlights if needed and when finished, turn off the engine. This final step will give you confidence that your off-road lights have been wired correctly and that you’re ready for any terrain!
