    Hey Guys, I thought we needed relay harness with our hids. I just installed a hid kit 8000k in heads using hi low kit on my 2010 dc.. Low hid and hi halogen and it seems to work fine np with no relay kit. everyone i talked to on here said i needed a relay harness. idk. do you guys use relay or are they only for the hid low and hid hi beam.

    What kit did you buy? A lot of the kits are plug and play so it comes with all the parts and pieces you need to make them fully functional.

    You'll have to put up some pictures of your set-up. Sounds like despite yourself, you've made a functional HID set-up :cool:

    Thats a plug in play kit and should work which in your case it does. You need a relay when you are using HID's in as an aux light such as if you put them in some off road lights. The relay acts as a safe guard so as your not sending all that voltage to your aux switch inside your cab which could melt wires and cause a fire.

    If you don't know what you are doing. But I like relays because the wires to my switches can be low current.

    Let us know if you happen to blow a fuse unless you upgraded your fuses to your headlights. In my old Integra I had them hooked up as you do and blew fuses every once in a while. May have just been a short. But I hooked it up via relay and didnt blow a fuse after.

    Having the relay has nothing to do with them working or not working. It has to do with protecting your stock wiring. They'll WORK without a relay. But you run the risk of potentially frying your wiring. Without the relay it's pulling power through your stock wiring, whereas with the relay it's bypassing that and pulling power right from the battery. Contrary to what a lot of people here often say, I'd NEVER run an HID kit without one. Especially with how cheap they are to buy. The ballasts draw a lot of current when they first fire up. For like 12 bucks, do yourself a favor and just get one to safe yourself from any headaches down the road.

    It will work but you run the risk of a melt down with out the relay if your not using the right gauge wiring. It depends really, Old cars with crapy small gauge wiring need a relay because the wire will not be able to handle the voltage. Newer vehicles may be ok because they use thicker gauge wiring. I would still use a relay to play it safe and that way your not running any risk. They are fairly cheap.

    i thought relays were for bixenon bulbs where both HI/LO beams are hid. i could be wrong though

    It's cool

    Okay, for a bixenon HID setup, the purpose of the relay is for high and low beam control. Without a relay, the HIDs would not have Hi/Lo functionality. What I am guessing you have is a set of ebay style headlights that have 2 light bowls in each housing. I am not sure if it is possible to run it so that the bulbs will go to high beam and at the same time the "high beam" lights turn on as well. Essentially giving you 4 high beams on the road.

    It is the wattage of the lights that make a realy needed.

    HIDs draw 35 watts (but produce the light of 150 watt halogens)... your stock halogen headlights are around 55 watts...

    A pair of 100 watt halogen off road lights need a realy, a pair of 35 watt HIDs don't.

    A relay is used so all that power doesn't need to go through the switch in your truck.

    Just fyi, you do know that HIDs with 8,000ºK color are far less bright then those with 5,000º color, right? Blue to violet might help you if you are from a planet with that color star... otherwise it is for looks only.

    Halogens are about 3,000º... (slightly yellow) and the best output HIDs are between 4,000 and 5,000º (pure white with a hint of blue) which is the brightest light color for illuminating the road ahead. Above 5,000º the color become too blue and looses brightness.

    Yea, but it's not the constant wattage that's the problem. They pull a lot more juice when they first fire up. I've seen these kits do some really goofy things(causing voltage sags bad enough to cause headunits to restart, etc.) and that's with a relay. I personally wouldn't want to assume that my wiring is good enough for that constant draw every time you turn your lights on. To each his own I guess if you don't want to spend the 12 bucks extra. Sure, the risk may be small, but until someone can confirm that the wiring is actually sufficient for them I'd never feel comfortable myself telling someone they don't need it. I'd be pissed if someone told me it's okay and then my wiring burned up.
