Headlight upgrade on CT is LED there is no OEM HID.
Lots of posts regarding HID install.

If you are a warranty worrier freak you probably won't do any mods.

Do your research and you won't have a problem.

DDM HID Kit, 55W, H11, 5000K
Bulb Type: H11
Wattage: 55 Watt
Bulb Color: 5000K

Is what I decided on, now to find someone that will install these for me.... I don't trust myself! Who can I go to? what kinda shop would do this for me? how much would they ask for from what I keep reading is quite simple install?

Thanks any input is truly appreciated.

I'm not sure our lens can handle the 55w? I've heard the Prius headlights deforming with the 55W.. Most choose the 35W

Great Choice

The original bulbs are 55w halogen H11 (see page 664 of owners manual). The HID bulbs produce less heat so there will be no problem; also there is sufficient ambient space to dissipant any heat produced. The only place it is caution not to use 55W is if you replace the fog lights, even though orignal fog lights are 55w. Since the original bulbs are 55w, then the low beams 55W HID will not draw more current ( ran into a problem on a BMW once on headlight electrical, melting connectors).

The kit you are getting is the same one I plan to get. There is no wire cutting and most people say they can do it in 30 minutes. It is un-plug old then plug in the new; simple no-brainer. Just make sure you connected to violet to the red. You might want to get some industrial velcro and some wire ties to hold the ballasts and make the wires neat. There is a thread with some pictures on this forum.

Changing the lights should have no impact on the car warranty. Worst case you can put old bulbs back in before taking in if a problem shoul occur, which is very unlikely.

I am torn between 6000K (bluer) and the 5000K. Apparentyl 4500K with a little yellow matches the DRL LEDs.

Good Luck!

55 watts is 55 watts of energy (heat) regardless of the source. HID's been installed in my wife's car for a while now (55 watt) no problems. I went for white color temp looks good.

Actually -from an Engineering perspective

55 watts is 55 watts of energy (heat) regardless of the source. HID's been installed in my wife's car for a while now (55 watt) no problems. I went for white color temp looks good.
You are transforming one source of energy (volt-amps) to another form of energy(light). The conversion is not always 100% efficient and has a by product heat due to impedence.

55 watts (volts times amperes; assuming no inductive or capacitive phase shift) = light enery + heat energy

==============
That aside, my dealer called an my car came in today an is being prepped.

Pick up tomorrow, Saturday, August 06, 2011 at 9:30 am :)

True - therefore 55 watt HID provides more light and less heat than 55 watt filament.

Conservation of energy cannot be violated.

HID 4500K or 5000K or 6000K

Audi4t - You chose 4500K lights. Is that the best match for the LED DLR lights ?

It looks to me like the 5000K are close to pure white and the 6000K have a nice hint of blue.

Could you please comment. Thanks ;)

Someone in another post observed that the daytime LED's drop in intensity when the low beams are turned on and appear "less" white.

I have noticed a similar appearance as though turning on the headlights reduces the brightness of the LED's.

This is probably why the daytime LED's appear yellower than the HID's.

Yes, that was me. :) Haven't you noticed it too? When I pull into my garage, the LED DRL's (only) produce a very bright source of light and shine up higher than the headlights. When you turn on the headlights, that bright source up high goes away. Further, if you look at the front of your car w/ those two options, the difference is very noticeable.

Yea it's true :(

On the IS250/350, people have modded a wire to allow the LED DRL to remain 100% brightness and it looks very nice!

Hopefully someone in the near future will have the guts to do this mod lol :p

I got the CT this morning and ordered the 55watt 6000K HID lights. The car is even better than i thought it would be- "CMYCTGO" - maybe ?

If Its anything like the other DDM kits i've used on other vehicles, it should be super easy. You really can't screw it up because all the connections only connect to what they are supposed to. There is one thing im curious about though.
The car is supposed to turn the lights on automatically once it starts getting dark. Will it still operate the same way with the HID?
