LED light bar plays a crucial role in night lighting. Before installing it on the roof, there are a few things to consider. This article will teach you how to wire a LED light bar without a relay. Yes, it is possible to connect LED light bars without relays. But you must follow the correct current, voltage, and resistance values to maintain the circuit.
Light-emitting diodes (LEDs) with higher color temperatures tend to be effective. First, choose the most suitable LED light bars. The average lifespan of an LED light bar is between 20,000 and 50,000 hours. Some reference factors include the light bar's color temperature, lifetime wattage, and voltage consumption.
How to wire LED light bar without relay？
Below are the detailed steps to wire the LED light bar without a relay.
First, find a suitable location to install the LED light bars. It could be the roof, front bumper, or even lower windshield, preferably with both wires. Once you have a location, drill holes in the area of your choice and make some marks. Be careful not to damage the rest of the car when drilling. Otherwise, use zippers or screws.
Next, wrap a wire around the screw on the back of the LED light bars. This will stick out far enough for easy connection later. Although not used in most cases. Then take another wire and wrap it around another screw on the back of the LED light bars.
Then place the bracket of the LED light bars in the correct position and fix it with screws. Be careful not to overtighten as it will have to be adjusted later.
Now, you need to locate the power side of the battery. Make sure it's not near moving parts or energy sources, creating unnecessary safety concerns.
Find a location where you can place the switch. We recommend that you install the switch in an easily accessible location. You can also use a remote switch. You need to make sure the power supply can handle the same voltage and wattage required by the LED light bars.
Installation with a remote switch would be quicker and easier but may not be necessary.
Use a tool to drill a hole the size of your switch. Plugin the switch and connect the wires. Once you have determined the appropriate power supply for the LED light bars, connect the switch to the power supply.
Connect the two ends of the wire to the negative and positive terminals of the car battery, respectively. You need to ensure the switch is off mode to avoid any mishaps.
Now that all the parts are connected, you need to connect the remaining parts with the harness. You should connect the ground wire to the negative battery terminal and the other side to the switch.
Once all the wires are connected and inserted correctly, look for any loose connections. Once this is done, tighten the installed hardware.
Next, double-check that the LED light bars are installed correctly. If all is well, it's time to test and activate the LED light bars!
After completing everything above, you have successfully wired a LED light bar without a relay!
