I've decided to retrofit my headlights with proper HID projectors and make some other changes while I have the headlights opened. I bought a spare set of 4cyl headlights that I'll be working with thanks to a kind member who happens to live nearby and had an extra set after his Touring swap. This is the first time I've done a retrofit or opened up a set of headlights so I'm learning as I go.

It turns out the 4th Gen Acura TL ('09+) HID projectors bolt right in place of the Accord's oem halogen projectors which saves a lot of the customization work that's usually required for a retrofit. I (hopefully) have a set on their way to me. They were listed as Acura MDX projectors on ebay but the pictures are identical to the TL ones. It was my understanding that MDX projectors are different, so either I'm wrong about that, or the seller had the wrong pictures up on ebay. I guess I'l find out soon enough!

I'm planning on installing a DRL strip light of some kind, getting rid of the amber colored reflector inside the housing (which I've wanted to do since I bought the car) and probably cutting back on the amount of chrome inside the housing (but nothing drastic).

I have 1 light opened up so far. Here is a pic of all the pieces that make up the headlight:



I ordered a couple things that will let me power my projectors/lights inside so I can play around with different strip light options and check the output of the projectors before I install them. I bought this 12V power supply and adapter from Amazon. It fired up a 55W HID ballast without any problem. Links below the pics:





I'm leaning towards an LED strip for the DRL. I ordered a cheap 16' roll of 5050 SMD led lights that can be trimmed to length. I'm guessing this is similar to what a lot of the pre-made strips are made from that people have been installing. They're bright indoors and probably visible during the day but I don't think they will really be great on a bright day. I mostly bought them so I can play around with them and find the best way to secure them for when I find the right ones. One thing I'm concerned about is that they run pretty hot. After running them for a couple hours the bottom of the plastic strip light housing that they were adhered to was about 130F and that was inside the house. I don't think that would cause too much trouble but I'm wondering if higher power ones might run too warm for this application.



A couple pics of them in the strip light housing. Note: I actually have 2 led strips inside the strip housing for this test. The reflective housing is tough to photograph because of all the chrome.



These aren't as blue as they look in the pic, but they are fairly blue. Probably about 6500k.


I've ordered a few feet of these which should be much brighter, whiter, and hopefully not too much hotter. http://www.flexfireleds.com/bright-white-high-intensity-ultrabright-led-flex-strip-light/

Bonus pic:
Output of oem halogen projector with 4300k HID bulb (35W ballast) from a couple feet away.



I'll update this thread as I progess.

I also sub'd..thank you for doing this...add a before and after (on table) so members can see the difference between what a real retro-fit and OEM halogen projectors look like. That glare is hideous on the oem...shhhhhhiet man!

Yeah the HID will be better but actually that's a pretty bad pic of the halogen projector. It looks a lot better from about 10' away and those weird artifacts way up high are from slots in the projector that are normally covered by a shroud in the housing. Plus the projector is pointed slightly up toward the wall instead of straight on. I'll get some better pics soon.

Now I have it figured out. TL HID projectors that bolt in are a great way to eliminate the issue of HIDs in a halogen projector.

That is a lot of work and I magine it is going to be well worth it.

Nice! Looks like you beat me to the punch, lol. :thmsup: I'll be interested to see your results with the MDX projectors. If they turn out to be the same, I may just end up cancelling my TRS order instead and opting for an alternative like those MDX's. My order got pushed back yet another week, and I am growing really impatient at this point. :nuts:

how long do you need to bake the headlight?

Depends on your oven, but usually it will be around 7 minutes at 200 degrees Fahrenheit. For your first time, if you are unsure of how intense your oven is, at about the 6 minute mark you can take the headlight out and gently pry the tabs open to see if they will budge. If not, you can put it back in for a couple of minutes longer until it becomes workable.

Make sure that the headlights are not touching any sides of the walls. It would be best to also prop them up on pieces of wood so as not to allow any metal to touch as well.
