FAQs

What's the purpose of a relay harness?

A relay harness helps control the flow of electricity in your car's lighting system. It ensures the right amount of power reaches the lights, improving their performance and protecting your car's wiring from potential damage.

What's the advantage of using a relay instead of a switch?

Using a relay offers several benefits over using a simple switch. Relays can handle higher currents, which is important for certain applications like powerful lights or accessories. They also help prevent voltage drop, ensuring consistent performance for your devices. Additionally, relays can be controlled by lower current switches, which can extend the lifespan of the switch and provide a better user experience.

What happens if a relay is not used?

If a relay is not used, certain electrical components in the automotive system might not function properly or may not receive the necessary power. This could lead to diminished performance, potential overheating, and even damage to the wiring or components due to excessive current flow. Relays help ensure the correct power distribution, protecting both the electrical system and the connected devices, and contributing to the overall reliability of the vehicle's operations.
