    Hey dudes. Do you guys think the lower led lights would look good on a second generation CTS? They look sexy on my XTS, but I don't have fog lights on my CTS. I wonder if the XTS and ATS lower lights are different sizes too.

    how do i wire them
    The DRL's run at 2 different brightness intensities, One is High for daytime and one is low for at night. This is why there are 3 wires on them Ground,High and Low. I purchased an ATS a month ago and will be doing the same mod as well as the headlamps.

    They would not fit, the ATS DRL is way too tall

    Technically they become parking lights at that point but yes they run at night as well

    Re: Finally intalled the OEM DRL and HID on a luxury ATS

    I have been looking into doing this to my ATS. I have the exact figures and part numbers but not in front of me right now. I did some research with some automotive collision estimating software to come up with one main fact. There is only one bumper used, therefore the lights are interchangeable between all levels of the ATS.
    All you really need are the following hard parts:

    Left and right --- what GM calls "driving lights" --- Can be found new for around $115 each
    Left and right --- bumper inserts --- one is around $45 and the other around $85
    Left and right --- Not sure what those little chrome bars are called --- around $60 each

    But Yohaishi may have answered the question that I have not been able to look at my ATS to figure out yet. He said that he wired them into the headlight circuit. I still need to get mine in the air to see if the plugs are actually there in the existing harness to power the lights. I have a hard time believing that they wouldn't be there but I also feel that Yohaishi had enough technical know how to install the lights he probably would have seen the connectors if they were there.

    A word about the upper led and headlight assemblies, to start with they are over $1000 each and replacement GM bulbs are $300 each, that's expensive. The other issue to think about is that those headlights are "adaptive" I am not sure that if you did spend the money they would function properly. I am sure that the Body Control Module would have to have the programming to operate the "adaptive" lights and that programming is probably not there. I think Yohaishi made a good choice in going with what appears to be an aftermarket HID conversion light kit for the headlights.

    If anyone is truly interested post a comment and I will come back and post all of the part numbers and list prices for the lower lights.

    Nice job Yohaishi !!! Mine is next !!![COLOR="Silver"]

    Yohaishi??
    Can you tell us what HID conversion kit you used??

    Re: Finally intalled the OEM DRL and HID on a luxury ATS

    So I finally got all the OEM hardware to install the lower LED lights on my 2013 2.0T Luxury ATS. I must say that the frontend looks "much" better even when the car is off. I felt that the bottom of the frontend lacked something before and now it doesn't. The cost of all the parts to install the lower OEM lights with shipping was around $380, but I feel that there was a significant "bang for your buck" with these lights installed. The connectors are "not" there on the front wiring harness so I wired them straight to the headlight circuit, yellow and black wires. So they are on when the headlights are on for DRL function and on at night as headlights would be. The connectors on the lights are 3 pin weather pack connectors so I managed to find a 3 pin weather pack connector located on two GM cars and used them to connect straight to the lights and soldered two of the three connectors to the yellow and black wires for the headlights. If you are interested in where to find the 3 pin weather pack connectors that work just find a GM car and look at the hood latch, it uses a 3 pin connector (I got two from two older GM cars). I did not install an HID kit in the car but I did switch the bulbs out with a pair of Putco Mirror White 4K bulbs. This gave me a little more brightness and turned the headlights nice and white to get rid of the usual halogen yellow tint. I installed everything through the wheel well, I did not remove the front bumper, it was a little tight to get the headlight bulbs changed but it is not difficult to do. It's just a little bit of a Rubic's Cube to get the cup covering the bulb on and off. The one pic with just one of the LED's on and both headlights is to show the difference between the OEM bulb on the left by itself and the Putco headlight bulb on the right. I also included a pic of the headlight wiring connector going into the headlight, it is the yellow and black wire you need to tie into.

    Here is the parts list and prices for my particular order, maybe you can find them cheaper.

    Part Number Part Name Price Quantity Total
    22787986 TRIM BEZEL INSERT $43.89 1 $43.89

    22787985 TRIM BEZEL $33.65 1 $33.65

    22787984 TRIM BEZEL $33.65 1 $33.65

    22787987 TRIM BEZEL INSERT $43.89 1 $43.89

    22913518 Daytime Running Light $102.91 1 $102.91

    22913519 Daytime Running Light $102.91 1 $102.91

    Subtotal: $360.90
    Shipping (FedEx - Ground): $18.37
    Total: $379.27
    Also add about $40 for a pair of Putco 9012 Mirror White headlight bulbs.

    I think it looks pretty good, let me know what you guys think. I am "very" happy that I decided to do this.

    Rnr4mula great write up thanks. I am about to pull the trigger and have a couple of questions. You mention there are 3 wires from the drl's and you connected them to the yellow and black as shown in the pic. Which two wires of the 3 did you hook up to the yellow and black? Also, when changing out the headlight bulb with a 4k bulb did you change out the yellow bulb below with a white bulb? If so can you provide that number of the bulb as I want to change mine out when doing this mod as I really don't like the look of it.

    Thanks
    Bill

    Re: Finally intalled the OEM DRL and HID on a luxury ATS

    My Cadillac dealerships are either ignorant or just dumb. They all tell me that I can't buy the HID's and LED's from them!? I don't think I want to attempt to install any of the components but can you tell me where you purchased the parts so I can at least take a look at the install and make the decision to take it to an installer?

    The only difference between your car without HIDS/LEDS and one with HIDS/LEDS is an order code. That code gets the correct parts and wiring harness during production. You probably can't get the wiring harness but you sure can get the parts. Any good body shop will ha ve them if your Caddy dealer takes a dumb pill.

    Do you think the headlights would of looked a bit better with the Nitro Blue instead of Pure White Bulbs? Seems like the DRLs have a blue light tint to them.

    The wires on the DRL's are red, blue, and gray. The gray is the ground and should be hooked to the black on the headlight wiring harness. It really doesn't matter which wire (red or blue on DRL's) you connect to the yellow wire of the headlight harness. Either one works the same if you are installing this on an ATS that did not come with them and the HID headlights. On the Halogen lights like on mine and yours the headlights are pulse modulated to a lower voltage to provide the daytime running lights via our headlights. So if you connect the red or blue from the LED DRL's to the yellow they will be pulse modulated down during daylight hours, they look pretty bright to me when they reflect on on car in front of me.
    I did not replace the yellow running and turn signal bulbs, maybe in the future.
    I will also add that I am very happy with the Putco 4K headlight bulbs I installed. After driving the car for awhile now I really notice how much whiter and further they illuminate.
    Hopes this helps you

    ----------

    Yes they are, and if you look on Putco's website you will find that the Pure White's illuminate much better.

    ----------

    I bought all the Cadillac OEM parts from here:
    GM Wholesale Direct

    The dealer just is not use to doing things like this, they told me the same thing. I used body shop collision estimating software to look up these parts by just selecting a Premium model ATS. The parts are interchangeable as yo can see by my finished install on my ATS. The HID headlight assemblies are another story as they are about $1200 each and require a $220 wiring harness to be purchased as well. The HID's just weren't worth that much to me especially because I didn't want the adaptive feature they have which by the way is not programed into the Body Control Module in your ATS.
    The lower LED's are not that hard to install and you have to splice into your headlight wiring in order to power them, another reason your dealer doesn't want to do it. There are no worries with this as long as all the connections are soldered and shrink wrapped to keep the weather elements out.
    Best of luck!

    They aren't offered as an accessory. That's why the parts department doesn't "see" them when they look it up. Have The body shop look them up as collision replacement parts.

    are there any talks of someone making a nice plug and play harness for this? I hate the idea of hacking up the wiring on a brand new car!

    I haven't found a thing on aftermarket gear. Everything is splicing or adding an additional harness....I went the adding stuff route and splicing into the existing wiring
