If you’re looking to install a LED light bar onto your vehicle, it’s important to understand the amperage draw of the LED light bar. LED light bars draw a substantial amount of power, and this can cause issues with your vehicle’s electrical system. Fortunately, understanding LED light bar amperage draw is straight-forward and can help you pick the right LED light bar for your vehicle’s electrical system.
What is Amperage?
Amperage is the measurement of the amount of electrical current flowing through a circuit. A circuit is the path of electricity that runs from the battery to the LED light bar, to the switch, and back to the battery. It’s important to understand that the electrical current must be able to run through the circuit properly in order to power the LED light bar. If the LED light bar draws too much current, it can damage your vehicle’s electrical system.
LED Light Bar Amperage Draw
The amount of electrical current drawn by an LED light bar is measured in Amps. A higher output LED light bar will draw more amperage, and a lower output LED light bar will draw less amperage. The exact amperage draw of a LED light bar depends on the size and number of LEDs used. For example, a 20-inch single row LED light bar with 30 LEDs will draw approximately 5 Amps. It’s important to note that the amperage draw can increase as the LED light bar gets older, so it’s important to check the amperage draw of your LED light bar periodically.
Calculating the Amperage Draw
You can calculate the amperage draw of a LED light bar by using the following formula: Amps = Watts / Volts. Watts is the power rating of the LED light bar, and Volts is the voltage rating of the LED light bar. For example, if the LED light bar is rated at 20 Watts and 12 Volts, the amperage draw of the LED light bar would be 1.67 Amps (20 Watts / 12 Volts = 1.67 Amps).
Powering a LED Light Bar
In order to power a LED light bar, you need to ensure that the LED light bar is connected to a power source that can handle its amperage draw. LED light bars are usually powered by a 12 Volt DC power source, such as a car battery or a power inverter. It’s important to ensure that the power source can handle the amperage draw of the LED light bar, otherwise it can cause damage to your vehicle’s electrical system.
Safety Precautions
When installing a LED light bar, it’s important to take safety precautions. Make sure that all connections are secure and properly insulated. Additionally, it’s important to ensure that the power source can handle the amperage draw of the LED light bar. If the LED light bar is drawing too much current, it can cause damage to your vehicle’s electrical system.
Conclusion
Understanding LED light bar amperage draw is an important part of installing a LED light bar onto your vehicle. Knowing the amperage draw of the LED light bar will help you pick the right LED light bar for your vehicle’s electrical system. Additionally, it’s important to ensure that all connections are secure and properly insulated and that the power source can handle the amperage draw of the LED light bar. Taking these steps will help you safely install a LED light bar onto your vehicle.
