|  | Cadillac Owners Member Cadillac(s): 2008 CTS AWD | | Join Date: Mar 2009 Location: MA | | | HID Conversion Kit I have an 08 CTS with the standard projector beam headlights. I'd like to install a HID conversion kit with 10,000K bulbs - is there anything special I should know? I know my current high / low beam bulbs are housed separately in the headlight casing, will this cause an issue with high / low Xenons? |

| | Cadillac Owners Member Cadillac(s): Cadillac | | | | | Re: HID Conversion Kit I changed out the factory HID to a better temperature bulb, one thing you need to know is you need to drop the bumper. That is the biggest concern. |

What do you mean by "better temperature"? |

| | Cadillac Owners Member Cadillac(s): Cadillac | | | | | Re: HID Conversion Kit factory HIDs are approximately 4,300k degree kelvin, which is a whitish blue tint, I wanted an extreme blue light, mine are upwards of around 30,000k which is a very deep blue, it is not as bright, but I have 20/10 vision and it is still very nice, I just wanted that custom look. These bulbs were engineered to be this blue, generally above 10,000k bulbs tend to look puple, but these are a dark exotic blue. http://rides.webshots.com/album/564112880HfMKZJ |

| | Cadillac Owners Member Cadillac(s): Cadillac | | | | | Re: HID Conversion Kit You will have to drop the bumper to be able to remove the headlights from the car and access the rear covers for access to the bulbs. Not real hard to do. Just time consuming.
The one drawback will be your converted HID lights will ALWAYS be on. Unless you pull the fuse for the day time running lights, they day time running light circut will also fire up the HID ballasts during the day. Its a simple fuse pull and problem solved if you want to do it. |

In this case, it's highly unlikely that you will lose your daytime running light. What usually happens is your HID's will flicker instead, causing a very short life-span on your capsules (bulbs). If you enjoy dropping your bumper and throwing away $$$, then this would be the route to take. I have read that you can purchase a relay and some sort of a wiring harness to override the flickering; however, it's my understanding that this kit takes away your daytime running lights completely. In Canada, daytime running lights are required by law. I would do more research on how the system in your specific model operates, and which HID kits are available for your application. Also, verify laws in your state regarding daytime running lights. Hopefully this helps! |

Maynor have you installed a HID conversion kit(s) for highs and / or lows? If so, could you point me in the right direction cause i'm having a helluva time getting straight answers out of any vendors. |

Oh, you wanted the "rice" look. Now I understand...
You sacrifice the safety for the "look"... |

| | Cadillac Owners Fanatic Cadillac(s): Cadillac | | | | | Re: HID Conversion Kit In my opinion, It will be much easier if you put HID on low beam headlamp and/or fog Light. Not in High beam.
Low beam headlamp bulb type H11 (OEM 55W)
High beam headlamp bulb type H9 (OEM 65W - No Ballastic)
Fog Light bulb type H11
The H11 bulbs are so popular but I don't know why H11 connectors are so expensive.
Please post how to remove the front bumper, step by step guide. Please....
