Do I need a relay harness for my HID kit?

If your HID kit does not come with a ballast, it’s highly recommended that you also install a relay harness. Going without either piece of equipment could do serious damage to your vehicle. We offer a variety of HID conversion kits that come with CANbus ballasts, so you don’t have to purchase a relay harness.

What does a HID resistor do?

Upon startup, HID ballasts draw more current than halogens to ignite the Xenon gas inside of the bulbs, once fired, they draw less than a stock light. The resistors ‘load’ the vehicle’s electric system and it ‘thinks’ that the halogen bulbs are installed.

How do I test my HID relay harness?

The primary function of an automotive headlight wire harness is to provide power directly from the vehicle’s battery to the lighting system. This allows the bulb, or HID ballast, to operate independently of the vehicle’s original wiring system and can provide a power source that is more consistent.

Can you run HID without ballast?

A ballast is essential in HID lighting technology because it provides the voltage to start the bulb and it also helps in maintaining an adequate flow of electrical current to the bulb. Simply speaking, a ballast is essential if you want to enjoy the real strengths of HID bulbs.

How do you set up HID headlights?

Step 1 Headlights.
Unplug the stock harness and remove the headlights.
Remove battery negative terminal.
Take out the HID bulb from the plastic shell and remove the circular plastic piece.
Screw in the HID bulb back into the headlight housing.
Before you mount the ballast, test the HID light to make sure it lights up.

Do I need a relay harness?

Sometimes if your vehicle has a low voltage issue, DRL or a CANBUS issue the relay harness will bypass the factory wiring and pull power straight from the battery. Also using a relay harness in your HID install is a good way to decrease the warm-up time of your bulbs.

Why won’t my HID lights turn on?

If one side sometimes doesn’t turn on it could be caused by a bad bulb, HID ballast, LED driver or wiring. Swap the ignitors to opposing sides (not applicable for LED kits). If the problem is reversed, you might have a bad ignitor. This step will check if you have a bad ignitor.

What is a relay wiring harness?

A Relay Wiring Harness utilizes a 30amp fuse protected power wire that directly connects to your positive terminal on the battery. An Automotive Relay is used to pull signal from a source (Headlight connector) that triggers power to be drawn from the battery.

Why do HID ballasts go bad?

In most cases, ballast failure occurs as a result of the surrounding environment. Heat and moisture are great enemies to your HID ballast. When it is too cold or too hot, the ballast can burn out or fail to start headlights. A combination of heat and constant condensation can also cause severe corrosion over time.
