I recently started to make relay harnesses for HIDs the main purpose of this relay is to add extra power to your HIDs rather than using your cars stock wiring harness, which you could potentially blow out over time along with your ballast due to insufficient energy being sent to your Ballast. One of the main reasons to get one of these is to take precautionary measure in your big investment. If you turn on your HIDs and it sometimes takes one side to warm up longer than the other side or one side will be a blueish color where the other is more green, this is a sign of needing a harness to supply more power to the ballast. So if you have HIDs I highly suggest looking into purchasing one. I am making these for $50 Shipped and you can see a picture posted below. I have seen similar harnesses sold for about the same price and more of lesser quality that does not take the extra step in protecting the relay and making decent connections with heavy gauge wire. I know this should probably be in the for sale section or a group buy section but I need to gauge the interest of those who have HIDs first. But if I can get more than 10 orders I will sell them for $40 Shipped.
