LED/HID Head Light Dust Cover Extension Mod for GM Projector Housings $2

I've recently started trying out some LED headlights, just because I enjoy trying out new things that I may find useful. In the process, as many know, the GM projector (and halogen high beams for that matter) have a dust cover over them. When converting to some HID and many LED H11 headlight replacements, the GM dust cover makes for a tight fit if it can be still used at all. So, I endeavored to modify the GM factory headlight dust covers to remedy this.

I wanted a decent looking outcome without spending a lot of cash. After trying various off the shelf "parts", I used the ever helpful process of "thinking outside the box". I purchased 4 GM dust covers for about $9ea which are used on many new GM vehicles:

Part No.: 23486492 COVER ASM-HDLP BULB ACC

I purchased these both to have potential spares for my other vehicle (2017 Chevy Colorado) or in case I needed a sacrificial prototype. . . In other words, buggered one up. But all went well and I made a couple pair. Of course, you can always just mod the ones your vehicle comes with and save $$. The only other items I needed were the "Custom Dust Cover Extensions" and some adhesive sealant to secure them to the GM dust cover after a bit of manicuring.

I initially tried some smaller diameter extensions and found it too much trouble to implement since the H11 bulb does not sit centered behind the GM dust cover. Therefore, I opted for a dust cover lobotomy and removed a good portion of it that yielded a lot of potential room. This leaves very adequate space for HID wiring/connectors, etc as well as the bulk of LED cooling apparatus be it cooling fans/fins or those braided wire strips. The pictures show an unmodified GM Dust Cover and the result after using a 1.5" hole saw to cut 3 overlapping holes into the top and then a dremel to finish out the rest. I am also thinking of adding a few ventilation holes with filter media behind them to allow more heat to escape from the bulb housing. The filter media will keep most dust out, but allow air to move through.

In all, the "Custom Dust Cover Extension" cost less than $2 each plus a little adhesive. I happened to have and recommend some automotive Goop brand adhesive which works well. It adheres to most plastics.

I am using some H11 LEDs which I will post here and are working very well. They are the best for the $$ I have found unless I wanted to spend +$80 to $100 or more. And these seem to have both a good low beam pattern as well as lighted distance ahead of the vehicle. There are a few that are slightly better, but then it is in the higher price range as mentioned. I found the H11 LED headlights I used for $35 the pair on 'Zon when they had a coupon price. Normally about $50. https://www.amazon.com/gp/product/B01MXMIRY6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1[/color]

NOTE:
[/color] By the way. . these H11 LED replacements require no capacitor or other wiring to remedy DRL flickering. They are plug and play.

2017 LED Headlight Reviews: [/color] - - -https://10carbest.com/led-headlights-bulbs

In reading the LED reviews, be mindful that things vary depending on the bulb type they replace. . H11, H16, 9004, 9005, etc. I noticed in the review listed here they use a 9007 replacement. The beam pattern on the H11 LED I bought is much better than shown in this review, and this Simdevanma LED H11 still comes up as #2 in Best for 2017 as tested in this review.

But back to the Custom Dust Cover Extension for $2. I thought I would have some fun and not divulge exactly what I used and let the forum members guess. I'll edit this and update for specifics so that others might do the mod.

I need to make a disclaimer. If you do not find this useful and not your cup of tea, that is OK with me. I do not need or want negative critics. I state this because on some other forums, and even this one at times, things are not appreciated by some.

Jay - What happens to the lights when they are in DRL mode ? Do they light at half power, or not at all ?

Also, I find that Silicone does not adhere very well to plastic,s but I have great success with Shoe Goo.

When will you tell us what the black cap is that you used ?

Re: LED/HID Head Light Dust Cover Extension Mod for GM Projector Housings $2

Hi . .

I used Automotive Goop. They also had Shoe Goop on the same rack as I recall when I bought it some time ago. Is that the same as Shoe Goo? Mine says "Automotive" on it. They actually have 4 or 5 different types now. Wonder if they are any different?

- - -NOTE:

Oh. . I am liking these LEDS. The first ones I've found for under $50 a pair that seem decent so far. And, in DRL mode the light ouptut seems the same as on night time mode, but I will get my meter out and measure it. I would say they are notice ably brighter than the stock halogen and also have a better spread. Center bright spot seems the same as my OEM halogens. While running with one LED and one OEM halogen I could barely stand looking at the orange/yellow of the halogen. I mainly wanted a whiter light and they are that as well as better spread pattern and throw seems about the same as OEM stock.

They have no extra "ballast" type box. Just a short braided cable and the mating connector to the standard H11. Cut off seems the same as the halogen OEM. I ran around for a week with just the driver side LED and the passenger side OEM halogen. They say a 2 year warranty. But who knows ?

So. . . you're supposed to guess what I used for the Custom Cap Extensions. . .. . I will answer tomorrow.

Stay tuned! ( This Equinox/Terrain Forum needs more people traffic. )

I once called them to ask that exact question, and they said they is a minor change in the ingredients, and for the most part, they are interchangeable. I just ShoeGoo, and never had any issues.

This isn't where I bought it, but this is the Amazing Goop. IIRC, I only paid $4 or $4.50 for it

Hi ,

About a 2" -3" cap. Could be in plumbing or water drainage "aisle".

Bigb12359 - - - - winner!

Sharp eye you have there. They are black plastic caps used on corrugated plastic drain tile. I found these at a local home supply store. Now, there are different brands of these and some are shaped differently.. These are Prinsco brand and ther are the 3" model EC03.

Here is a link with the brand and model number. And a couple of places to get them.
