I am considering attempting this...

So I am ready to purchase a second set of GXP Headlights lol

that way if I fubar it im not stuck.

I would like to however buy a set of Projectors from Ebay then just mold everything together..

Looking at them I think using a set of 03 GP lights is closer then an 05 ???

Could I maybe have a Member take some measurements for me ?

03 style GP



05 Style GP




Bonneville GXP




hmmmmm Will likely be a winter project... I just think putting the both together will finish the look

I seem to remember someone doing this project. I believe he did a write up and I put it in tech info, but don't remember where.

I think this was it. https://www.gmforum.com/showthread.p...ight=projector Hope this helps out.

i looked as well....

read that one !!

im thinking about molding the complete housing not just the projectors, will give it a more finished look

Hmm good luck on the molding, that'll be A LOTTTTT of work and time. I don't forsee trying to combine a set of projector headlights from another car into the Bonneville headlight coming out with good results. Best bet might be to retrofit projectors and then try to make a shroud to fill in the space between the black plastic frame and the projector.

I can't see how it would be more work,

Cutting,fitting and then filling in to give a retro fit a finished look, Then always having to remember where your retro fit projectors came from ( replacement Bulbs )

Or finding something as close as possible then making it fit.

I can buy 03 GP headlights for approximately 60.00 a side New. Maybe starting like that will be the way to go, Measuring then Measuring some more prior to cutting just to get the fit right.

Don't get me wrong I love the retro fit, Just like to do something Out of the box.

Its all about finding the right Projector bucket to start with

i wouldnt even think twice about retrofitting aftermarket projectors into my bonne headlights as they all have a really shitty cutoff line,
i had projectors installed on my 03 GTP before and i had few problems, major two were the projector bouncing back n forth and also the cutoff line was very very bad

if you wanna do a retro buy some good quality and recommended projectors, everyone i called and talked to about retros they all recommended the TSX projectors, someone on another forum used STS projectors into theirs bonnneville, you can also do a bixenon setup by using inifiniti FX projectors

again, if you wanna be happy with the results, do not use GP or any car'* aftermarket projectors.

just my $0.02

Yutzy did my retro with TSX projectors. They are awesome, bulbs are easy to find too. I think this route is the best.

Yea I've been missing that set of headlights lol. Hopefully I can get another set made here before too long
