This special HID single beam relay harness is one method of avoiding any mechanical and electrical problems and in some vehicles with flickering problems in your vehicle. It can draw the power from the battery and not from the vehicle’s electrical system and deliver to the HID ballasts; and not going to short your vehicle circuit. The long wire is covered with poly synthetic to prevent any damage from over heating. This relay harness was designed for cars with 9006 and 9005 single bulb types. But it could be used on any HID kit that is single beam with some modifications at your discretion.
What does a Relay Wiring Harness fix and Why it is important to have one?
An Relay wire harness is capable of fixing a variety of power related HID lighting issues i.e. intermittent on/off, flickering, delayed start, HID low light output, and uneven brightness.
Problem: Delayed Start
An HID Ballast requires more power to ignite on startup than during normal usage. This initial power surge can sometimes be problematic for vehicles with weaker electrical systems that cannot provide the power needed. The vehicles stock headlight connectors are not capable of providing 7-8 amps per headlight and as a result, only one HID turns on when the switch is turned on. After about 20 seconds when the ballasts power consumption drops to 3.2 amps, you can quickly turn the lights off then back on and voila, both HID lights turn on. This scenario happens all the time and is the direct result of insufficient power.
An HID wiring harness with power supplied directly from the battery would eliminate this issue as it would be able to consume up to 30 amps through the batteries positive terminal to ignite both ballasts.
An HID Ballast that is not getting sufficient power from a stock headlight connector will cycle on and off as it tries to ignite and power on. This can also be a result of an inefficient ballast that is not able to convert the available power to properly ignite an HID system.
An HID wiring harness will provide the power necessary to ignite even an inefficient ballast for flicker free HID lighting.
Problem: Dim/Dark Light Output:
When a ballast is underperforming, light output can appear more blue and dimmer than it should be. This is a result of the ballast not converting enough power to ignite the bulb at its optimal range. A bulb that is 4300K connected to a ballast with a weak power source, can look like an 8000K blue color with substantially lower light output.
An HID Wiring harness will be able to provide more power to the ballast allowing the system to operate at 100%. This however is not a guaranteed solution as a poor quality ballast will not output sufficient power no matter how much is being inputted.
Problem: Uneven Brightness
My passenger side is brighter than my driver side! Power in not always delivered in equal amounts to each headlight, and depending on your vehicles wiring configuration, can have a negative impact on lighting performance when installing HIDs. If one headlight has less resistance to the power source i.e. less bends or curves in the wiring, length of wiring, fuse panels bridging connections etc, it will receive power first leaving less for the second headlight to consume. In this scenario, one headlight will end up brighter than the other.
Solution: An HID wiring harness will provide equal amounts of power to each HID Ballast allowing for even and consistent brightness between both headlights.
