HID install

Most vendors that sell HID's for the C5 also sell the inline resistors that work with them. I know JWMotoring sells them.
Here's a bit of background for you as fuses are something every car owner should learn about...
The C5 has two fuse boxes in it. One is under the hood in front of the battery, the other is below a removable kick panel at the frontmost section of the passenger side floorboard.
Every electrical circuit in your car has a fuse wired into it. The purpose of a fuse is to protect the more expensive components within that circuit from electrical surges where the current flowing through the circuit exceeds the safe voltage rating for the component.
For example, your stock headlight circuit has a 10 amp fuse wired into it (located in the fuse box) because that circuit should never need more than 10 amps to operate. The fuse is only capable of conducting current at or below 10 amps. If there is a surge in your electrical system and the voltage in that circuit exceeds 10 amps the fuse will "blow" which cuts off the flow of current through that circuit and protects the other components in it. At that point you'll need to replace the fuse. If you ever have a minor electrical problem in your car such as a headlight out or a component in the cockpit not getting power one of the first steps in troubleshooting the problem is checking the fuse or fuses that correspond to that system. A fuse can be replaced in about 30 seconds and usually cost just a few cents each.
If you have any problems with your install post up on here and someone will help you out. Good luck

You won't blind traffic if you aim them properly; I have yet to get high beams flashed at me by a single person. After I installed them I had a friend drive past me while I sat in another car to make sure they weren't up in people's faces.
That said I have a set of ACA knockoffs I bought on the auction site sitting in the garage waiting for install. It is a BETTER solution but if you do the swap right into stock housings you'll be fine. There are literally thousands of C5 owners that have done it.
i installed a set of the projector "knockoffs" and never looked back. i used 55w ddm HID's and what a difference compared to stock lighting. honestly the stock lights on this car are comparable to my beater civic which is really sad.
the install is very straight forward. just make sure you have everything grounded before you go turning anything on... there should be 2 grounds IF you use a relay (which you should) its much more reliable and much more efficient if you do so. its plug and play really, i had my old headlights out, installed the hid kit including ballast bulbs etc and reinstalled the knockoff projectors in less then an hour total.


my son installed HID's in the stock headlights for me and it is far from "Ghetto".....If I remember correctly all he had to do was switch the 10 amp fuse to a 20. The only thing that is different is I used to be able to turn the light switch off in one motion.....now in order to get the lights to go down I turn the switch one click at a time ....takes maybe .05 second more if that. I have never had anyone flash their lights at me because I was "blinding" someone.

Son installed Korzen's....not sure if they are considered good/bad/better/worse...but they look great and again...not one person in years has flashed their lights at me and I do see signs much better and sooner.
They are ok in my book.

Would this just require another kit?
I'm thinking of performing this mod also and would like to change both low and high beams to HID. My wife's Nissan Maxima has high/low HID's from the factory and they are really nice.

the "right" way of doing this is to use the hi/lo bulbs. its a single bulb with both functions. if you just install another hid kit for your highs it will go bad really fast. the worst thing you can do with an hid is to turn it on/off. now if you can find someway to keep the bulb dim lite while the high beam is "off" then you may be able to get away with it... its something ive always wanted to try but could never figure out how.
