DIY - Third brake light relocate to headliner
 

UPDATE 4/1/14: Tint tests added on third page.

TL;DR
I made this:

And it looks awesome:

The third brake light in this car has always bugged me. It’s in the way and it’s ugly. So I moved it. I used basswood and aluminum because they’re very easy to work with and I bought an LED strip from SuperBrightLEDs.com. The strip I got is 18’ long and very thin (it had to be to fit in the thickness of the headliner), and it has it’s own housing with a diffuser on the front so no individual LEDs are visible. It’s a cool looking light.

Speaking of thinness, one of the goals of this project was that I wanted an unobstructed rear view, so it was important that the entire enclosure be very thin so as little as possible is visible from the rear view mirror. It ended up that it is completely invisible, so it turned out really well in that regard.

Another requirement was that it not be attached in any way to the window, and that the new brake light be easily removable for tinting or washing the window. In this regard, the enclosure is attached with a small aluminum panel with just the center clip holding the headliner to the roof. To the process of making and installing…

Materials:
(2) 1/8”x4”x24” basswood from Michael’s or craft store
Various #6 screws, nuts, and bolts from Home Depot
Rattle can flat black spray paint
12”x24”x.019” mill finish aluminum sheet (I had a lot left over)
18” red 12vdc LED strip from superbrightleds.com
3m extension cable for LED strip

The design was the hardest part because it had to fit the window well enough that almost no light passed between the enclosure and the window, illuminating the rear deck. This is where the basswood came in handy. Using just a utility knife, I could cut, hold it up to the window, adjust my measurements and cut again. Here is how the basic frame came out after cutting it a few times:

And with the LED strip in it:

I don’t have much to talk about in the way of actually building the thing. I just used a little trial and error and put it all together with super glue. If you use super glue, let it sit out of the car overnight to dry before painting. If you leave it up against the window before it cures, it will off-gas and leave a film on your windows that will not come off. I then painted it flat black, attached the light, and put so self sticking felt on the edges and anywhere I though it might rattle up against the window.

The important part is the aluminum bracket I made to hold it up.

I made this so there would be one point of attachment for ease of installation and removal. I cut about a 4x5 piece of 1mm thick aluminum and bent it up and over the back lip of the headliner. It attaches with the center clip of the headliner through the hole into the roof (look back there, you’ll see what I mean). The important part is bending the part that the light enclosure attaches to so that there is constant pressure against the window. You want pretty solid pressure because if not it may separate and tap the window when you drive over large bumps in the road. Here is the whole thing finished:

I also added some screws to the ends to press against the headliner to keep the whole thing from wobbling and help with the pressure against the window:

Ok, now the installation. I followed this wonderful thread to remove the rear deck. It wasn’t necessary just to run the cables as they can just be tucked behind the panels around the window and the headliner, but since I really want that stock third brake light gone, I had to take the deck out. Yes, I had to remove almost all of the panels in the rear just like in the DIY linked above to easily get the deck out and back in.

Once I had the deck out I drilled the plastic rivets holding the brake light on and removed it:

“Nooooooooooo!”

Unhook the OEM cable from the LEDs on the stock brake light.

I also bought the 3 meter extension cable for this LED strip from SuperBrightLEDs here:

Cut it to the right length (sorry I didn’t measure before putting it in the car, you’ll have to route it then cut to the right length) and attach the two wires (however you see fit) to the OEM cable. I just put two small blades on the extension and plugged them into the OEM cable leads. Super easy and reversible. Then I wrapped it with padding so it wouldn’t rattle around:

This is how I routed the cable:

From here mounting the light is simple. Pop the three clips holding up the headliner up in the back. Side note: legitimate panel removal tools make working on projects like this 10x easier. Attach the extension cable, pull the headliner down, and slide the bracket in, lining up the holes.

The connectors sit nicely outside the headliner in the the open area on the enclosure toward the front of the car. Push it up to the roof (remember because it’s bent to have tension) and pop the center clip into the headliner. Pop the two side clips in.

As for the rear deck, I don’t have any pictures showing me covering it, but all I did was get some Krylon All-purpose 7010 spray adhesive and glue a large piece of felt to it. I also cut out the areas for the carseat ring covers:

Yay! No more stock third brake light!

Reassemble everything and that’s it. After this I drove around and tweaked the new third brake light to get rid of some rattles by covering the aluminum with thin black fabric. Here’s my new rear view:

So good!

And here’s the final product:

I think that’s about it. I love how it turned out. It looks almost OEM and that’s how I like my mods. I'll post some night shots later.

Night shots!

Awesome.

Classy.

sub'd

I will be doing this as I have already swapped my rear shelf with a light delete... Great DIY

Lightweight as well! Love the idea.

Think if you covered the wood in vinyl it would look more OEM...right now you can tell its wood...that would bother me...but otherwise great idea.

Really theres palstic you could use...called sintra, its a foam based plastic cuts like balsa even.

I will look into this. You can tell it's wood when you're close, but it's not as bad as it looks in the pictures. However, I'll always try to make it better. Thanks!

It would bother the hell out of me, Im sure no one else would notice but its like that small ding or chip that isnt noticable you know its there but no one else does

I checked out that sintra stuff and it looks great except it can be heated and molded into a shape with as little heat as a hair dryer puts out. Probably not the best thing to sit in the sun for hours in a 150º+ car. I may eventually look into covering it, but that would make it heavier and slightly thicker. Not much, but maybe enough. Right now it's nice and light, and I don't want to do anything that might make it rattle against the window.

I like that a lot. I recommend wrapping it like you did the rear deck. It would look OEM.

Thinking of making some and selling them?

@fatherfork it would be great if you could make me one too. I can buy the other stuff like the led strip and extension and bolts, but if you could make me the wood and metal frame part that would be super awesome. PM me if you'd be willing and I'll pay you $$. :) I don't have the right tools to do the metal and wood.

If this is a possibility pm me too!

@fatherfork Well done my friend!

Thanks! And thanks for the plastidip suggestion. I'm going to try it.

How much interest would there be if these cost about $100? This would include the light and all hardware. It would be plug and play.

that is a good price I think

Yes sign me up. I'm ready to pay you! :)

Perhaps you could wrap in alcantara??? Just a suggestion...


EDIT: Forgot to add... Awesome job! The night shot really looks good! Why didn't Subaru/Toyota do this?!

Awesome! I am down for it for the $100 you mentioned as well.

I would definitely support this being $100! This is awesome work, great job!

nice dude, clean job
gana be doing this also, but longer. (closer to how it looks on the Tesla)

If you could sell all the necessary components (including the felt wrap cut to size for the rear deck, and then also wrap the wood around the light) I would be all in if it were plug and play at $100.

Just make sure to watch how you do this so you don't get banned...

Great job, I'd definitely be down to buy one off you. Your windows don't appear to be tinted. Do you think that LED bar would be bright enough to be noticeable behind a 20% tint?

I'd be in for $100!!
- a really nice, clean solution to correct a futzy design element

THIS! Do not sell/advertise/mention/allude to them on the forum without paying the vendor fee, otherwise you'll get banned and permanently barred from having PMs and a signature. Been there, dealt with that, still living with it.

I'd pay that for one!

count me in for one also!

Nice, someone did a DIY for you.

Thank you. I have been thinking about this.

To be clear (with the admins), I have no current plans to make and sell these. I am not a vendor and do not intend to play one on TV.

I will not, however, rule it out for the future. I'm glad you all like it. I smile every time I look in my rear view mirror.

It will be visible, but I really doubt I would use this particular LED strip behind 20%. I do plan on getting 35% soonish, so we'll see how that goes. I may have to source something a little brighter, but I think anyone who wanted this and has as low as 35% would be fine with this strip. As always though, check your local laws.

Edit: The only reason I wouldn't use this strip behind 20% is because of daytime driving. At night I'm sure it would be plenty visible.

Thanks! I went with the shorter light because I like the strait line. All the way across can look good, but it's harder to get the curve right.

This is sexier than I would have expected!

I think I am going to use this idea rather than getting the beatsonic spoiler to do the same thing. much cheaper less 'ricer' option (since cops love giving me tickets as it is).

edit1: Although, I am going to try to do it across the whole back of the car and put in some turn signals!
edit2: Alcantara would be really sweet, it would help fill the little gaps that are left after cutting the wood. Might have to pick up some of that too.

Subbed!

Wow, that looks awesome - nice work!

Definitely adding this to my list of future projects.

count me in for one, and I'm willing to pay extra shipping fee to taiwan

Just a quick update guys, thanks for the interest. I wasn't planning to build these, but I'm looking into forum sponsorship now so we'll see what happens :-)

Woohoo!!! Glad to hear. This looks awesome :bow:
