I ordered and installed a HID kit on my GXP like 2 weeks ago. I read someone else did the same thing on here too? Anyway I am pretty happy with the light output and have not been flashed by anyone yet and I do alot of night driving. corvetecrazy is right that the pattern is not that great and projectors would assist greatly but what can you do. Some awesome camera you go there btw. I chose 6000K bulbs and I am really happ with them. They put out a white light with a slight hint of blue. Just enough to let you know they are HID. good luck with your HID install and let me know if you have any questions.

I to noticed that the light pattern is a little different. It does seem to go a little further on the right hand beam. I can definatly see road signs alot further down the road. Also the lines on the road seem to stand out alot further. I was on some backroads last night and I was able to spot a group a deer alot sooner then I used to be able too and that was without my hi beams. Their eyes seem to blow alot brighter with the HID bulbs.

Update. Another one of my silverstar High beam just burned out last night. Maybe because my friends were amazed at the color of my lows they were kinda flicking my highbeams on and then laughing at the color. I'm going to put the other new nighthawk in the light that burned out and I will also put another new silverstar in the one that currently has a nighthawk to check if it is just that headlight that likes to burn out bulbs.
I will keep updating.

flickering HId is bad for the capsules.. to certain extend.. the ballast

On the 2001 bonneville when you put on your hi beams it doesnt turn off the low beams so its not bad flicking between the two.

Oh.. ok.. NEver knew..
I know mine does.. but it'* Pre 00. Did you run separate wires for the ballast or did you run it straight thru the actual headlight power wires?

I"d recomend runnin separete power wires.. but to each their own.

The kit that I got works off of the stock wiring harness in the headlight assembly. They only use 35 watts instead of the stock low beams that draw 55 watts, so it shouldn't damage anything...hopefully

they only draw 35 watts while running, thow an amp meter on them when you fire them up cold.

I never thought about doing that. I don't have an amp meter, but my 2 of my friends might they are electrical engineers

Murdock..do you owe us a write up and pictures?

As soon as I can do the FWI so it won't affect my performance..
