Wiring Gauge

Wiring gauge is a critical component of LED light bar wiring diagrams. It determines the appropriate thickness of the wires used in the system, which directly influences the efficiency of current flow and the overall performance of the LED light bar. Thicker wires have lower resistance, allowing for better current flow and minimizing voltage drop over long distances. This is particularly important for LED light bars that are mounted on vehicles or other applications where the power source is located some distance away from the light bar.

Wiring diagrams specify the recommended wire gauge based on the power requirements of the LED light bar. Using wires that are too thin can lead to excessive voltage drop, resulting in reduced light output and potential damage to the light bar. Conversely, using wires that are too thick is unnecessary and can increase the cost and complexity of the installation.
