Halogen upgrades.

Too bad there is no HID option.... so I'll have to make one myself, for the low beams. In the meantime I'll have to upgrade the halogen bulbs to something a little more acceptable.

So far the most intensive mod I have planned for our new terrain is to modify the headlights to accept a proper HID ellipsoidal setup.

The headlight designs themselves are quite different, but I'm curious to know if GM managed costs a little better by using the same halogen projectors in both the Terrain and Acadia, and/or other models. Which would mean that the Acadia HID lens/reflector would theoretically fit in the Terrain....... The first step will be to find out if they have the same part numbers I guess.

Barring that, I may pick up a set of AP1 Honda S2000 headlights, since they are by far my favorite as far as spread and cut off are concerned.

Or I could just buy a quality HID kit and pop them in, but that will depend on what bulb type GM uses in the projector housing. If the focus point looks like it will be very close between the halogen and the xenon bulb (like it seems to be for the Acadia), then I may just go this route.

Re: Too bad there is no HID option........

True, you would think HID would at least be an option. Good luck on your mods to your new Terrain. The more I hear about the Terrain, the more I like it. Not in the market just yet, but really think the Terrain will take off. Glad to hear you got one, hope you like it for years to come. I have a 2009 Enclave, and have had that a year, and it's great. The Terrain has some of the features of the Enclave, plus a few more newer goodies, some I wish were on the Enclave. You will like HID lights if you are able to do the mod, keep us posted...and enjoy that new ride!

You might check out XenonDepot, one of the sponsors in the Lambda forums (http://www.acadiaforum.net). He may have replacement HIDs for these as well. It's worth a shot.

Re: Too bad there is no HID option........

Our new Terrain finally came in at the start of the week. The lighting situation is as bad as I thought; with the low beams and fog lights being piddly 1400 lumen H11 bulbs, things definitely need to change.

First things first. I ordered some of these newfangled Toshiba/GE HIR 9011 bulbs for the high beams ( they will have to be modified a little bit to fit in the 9005 socket). From the before and after images I've seen, it should make worlds of difference. The OEM highbeams are pretty decent, but I like to be able to see very clearly, especially with the many deer and antelope who live around here. The lights have been ordered from www.finemotoring.com.

I considered using H9 bulbs in place of the H11's in the fog lights, but I couldn't find anything that I liked. Apparently H9's are still quite rare, as far as bulbs go. So instead I have ordered 2 sets of Osram Nightbreakers from www.powerbulbs.com. I've heard excellent reviews (supposedly 90% more available light), so we'll see how the do in the fog lights.

I'm also putting a set of these Nightbreakers in the low beam headlights for now, it should be at least a livable improvement for over the winter. Eventually (read: when it warms up next spring) I'll be doing a HID retrofit. I'm not a fan of sticking modified D2S bulbs in housings that were not designed for it. I'd rather do it right. The retrofit will basically consist of Hella Gen 3 ballasts, Philips bulbs (4300K), and The Retrofit Source's new Honda S2000 replica projectors (when they finally finish them).

Anyway, I'll post pictures of the installation(s) and changes in output as I get there.

Oct 30th:

I received all of my bulbs in the mail. After reading the Acadia forums, and how inefficiently they were designed with regards to headlight access, I'm glad someone heard the complaints. Access was easy; a nice little port hole to reach through in the wheel well. Even the dust/moisture caps on the headlights themselves had a little bar to grab onto for twisting them on/off.

The H11's are a little brighter. Not too much difference, but as I said before it'll have to do for now. The HIR bulbs seem to make a lot of difference, especially once they've heated up fully.

Fog Lights: Before and After



Low Beams: Before and After



High Beams HIR: Before and After



Before and After pictures were taken using the same settings, in the same environment, in the same night, with the same camera, within a short period of time from each other, and with no photoshopping

Mobius, we look forward to your project! When you start, I suggest you create a new thread and document your project. If history is any indication, that kind of thread will be highly sought after in the months and years to come.

Re: Halogen upgrades.

Great info! Thanks!

I too had read nightmares about replacing headlight bulbs on late model gms. Glad the engineers provided relative easy access to them.

Still waiting for my Terrain. It's "in transit" whatever that means.

Re: Halogen upgrades.

Does anyone know if there is a way to disconnect the daytime running lights when using the automatic feature. This would hurt the life of the hid bulb.

Re: Halogen upgrades.

I haven't really looked into that yet, but I assume there would be some method of doing so. I also assume that by 'hurting the life of the HID bulb', you're talking about it being reduced by them being lit for long periods of time?
