Step-1: Mounting location

The first step is to install LED light on your vehicle and select the suitable mounting location. You may think to place it in a vehicle bulbar, roof case, or other suitable place where you feel comfortable. But it is important to know the regulations on installing driving lights. It may help you to avoid the hassle with the traffic authority.

Step-2: Proper drilling

After selecting location, you need to drill the right size holes to mount the light bar. Prior to drilling make sure any part will not be damaged due to drilling.

Step-3:  Select the LED

Light Emitting Diodes (LED) depends on color temperatures and lifespan. Higher color temperatures are usually effective. It runs between 20,000 to 50,000 hours. It makes the scene have a lower color temperature and lifespan is low. 

Step-4: Power Supply

Usually batteries are the main source of power supply.  You have to determine whether the batteries you have will cover the wattage and voltage for the LED you are going to install. Make sure the LED has the same value for voltage and amperage.

Step-5: The Resistor

Before determining the resistor that you are going to use, calculate the voltage and amperage. Because, high current values may cause the LED to burst.

Step-6: - Wire LED Light Bar to Switch:

When completing the steps mentioned above, you should carefully do the followings to wire LED light bar to the switch:

  • Use copper wire to connect one side of a respective resistor to one terminal of the switch and make sure the switch is in an off position. Solder the both ends of this copper wire to the switch and the resistor.
  • Now you may connect the other end of the switch to the positive side of your power supply and the soldier both ends. Positive (+) sign to be mark end of the power supply
  • Connect the cathode of the LED with the power supply and solder both ends.
  • Now turn the switch ON and check your LED Lights.

In order to doing the whole things you need the following:

  • Driving light
  • LED light bar
  • Drill, bits, self-tapping screws
  • Electrical tape

Step-7: Location of Switch:

Find the suitable place in your car where you can switch easily. Strategically you should mount the switch inside of the vehicle. While driving you should not want to take your eyes off the road just find the switch.  To improve the efficiency and speed of the installation process, you may also use a remote-controlled switch for better service.

Step-8: Harness

Now you need to connect the ground wire with a large terminal to a negative battery terminal from the harnessWhen you do this from the harness, connect the power (or red wire) with the large terminal to a positive battery terminal.

Step-9: Disconnect Negative terminal

Safety is the first priority. So to ensure the safety, detach the wire from the negative terminal of your car battery before doing anything. Otherwise you could suffer from electric shocks. In order to avoid losing your radio stations, you may connect a memory reminder to your accessories.

Step-10: Final Checking 

After completing the process till here, re-check all the electrical connections. This final step includes tidying up the system and ensuring safety. Carefully find and make sure, whether any loose connection or naked wires and plugs are found. So immediately tape-up and tight the loose connection and plugs. 

Finally, after all work is done, reconnect your negative terminal to your battery and double check if you have accomplished everything correctly before testing your LED light bar.

Now you need to aim your vehicle's fitted LED light bar in the appropriate direction. In this process you can see how to wire offroad lights without relay.

LED Relay with its Advantages & Disadvantages

How to install LED light bar without relay

Prior to knowing the Pros and Cons of LED Relay, you need to know what is Relay? 

Relays are electric switches that use electromagnetism to control the electricity in high current circuit loads. These conversions occur when electrical inputs activate electromagnets to either form or break existing circuits.

Mainly it is leveraging weak inputs to power stronger currents. The relays effectively act as either a switch or an amplifier for the electric-circuit, depending on the desired application.

Advantages of Relay

  •  A relay provides a low current circuit to control the electric flow in a high current one.
  • Overheating of the switch may sometimes occur in cases where a relay is not used. It can lead to dangerous situations. So using a relay is safe.  
  • In absence of a relay, the control switch is unable to handle the full current of the LED light bar and thus problems arise. In low powered LED lights, the problem is hardly noticed but in case of high power it is really difficult to manage.  As a result, difficulties like melted wires and heating of the switch more than the optimum level occurs.
  • Without a relay, full current of the LED light is not managed and the light is feeble. Bright light is only possible through relay. For this reason, relay is preferred to be used in LED lights.

Disadvantages of Relay

  • Relay parts are exposed to extreme wearing and tearing and may cause ignition of sparks between the switch contacts. The sparks are noticed when the voltage and current levels are higher than optimum level.
  • They are of no use in micro-electronic circuits due to absence of high current. As a result, additional circuitry is required in their cases.
  • The coil can be damaged due to the back-emf created during powering off the relay coil.
  • They show a fairly slower response.
  •  Due to the slow type of response, they cannot be used to turn the switch on and off at rapid speed. This is a major drawback in case of relay. In such cases, relays are to be avoided to be used in wiring LED lights respectively.

Final Words

Wiring the LED light bar in front of the vehicle makes an easy view clearly while driving at night time. In fact, this is a very complicated process. Although this article will help you how to wire LED light bar without relay. If you really want to do it, our suggestion is to contact a professional electro-mechanic for better fittings.
