WK (and possibly others) LED lighted cupholders
**** And we are live!

Okay guys, as promised, here are a few pics of how I made and installed my lighted LED cupholder rings. Had I known the response would have been so positive I would have documented things a little better. I think you'll get the gist of things though.

I'll start by saying that this isn't exactly easy to replicate unless you have access to a CNC. I build small form factor computers as a hobby, and I make frequent use of the CNC for those projects. I've only now started playing with it on other projects. It's small, but more than adequate for the work I typically do.

I took a few measurements and came up with a simple design in CAD. I converted the design for milling and pulled out some 5mm acrylic I had left over from a previous project.

I clamped it to the CNC and let her rip.

A few minutes later I was left with a small disk with a recessed pocket.

With the backing peeled...

I used Little Dot SMD LED Accent Lights. They are pretty cheap, and already have the resisters built in, along with substantially long lead wires. They fit perfectly in the smaller pocket I milled in the disk. In this pic you can also see I lightly sanded the surface of the acrylic disk. I did this to help diffuse the lighting a bit.

Although I didn't get a picture of the disk insert being made, it's simply a piece of 1mm PVC sheet. The tolerances are very tight, but the insert just presses in place. Once there, it's not ever going to fall out on it's own. In fact, I had tap on it a bit with a rubber mallet to get it seated.

A test lighting... and success!

I basically repeated the same process above for the second cupholder with a slightly larger ring, since they aren't the same size.

Now, in order to get them seated in the cup holder, I had to do a little trimming of the rubber. Using a very sharp x-acto knife, I just made the bottom openings a little taller. I really only needed to take a few mm out.

Lastly was the wiring. I tapped into the 12v switched auxiliary plug (left) on center console stack.)

As far as wire routing went, I just ran a wire to the left and right of where the rubber on the front of the cupholder 'snaps' into place. I didn't have any at the time, but I'll likely go back in and add a simple plug to disconnect the wiring should servicing of some kind be needed.

Overall I'm pretty happy with them, although I'm going to try and tone down the boldness of the green to match my instruments. I've ordered some white LED's and some colored filters to attempt this. I also ordered a simple PWM dimmer to play with. Either might get me the results I was looking for.

Now, some of you have expressed interest in me having a few of these fabbed up. I'd be happy to do that. I'd need to get some more materials and LED's. Just let me know! :D

**** Update! Check this post for the first color samples with a white LED and gel filter.

**** Update 2! Check this post for the second color samples with colored LED's.

**** Update 3! Check this thread for an informal poll on colors.

**** Update 4! Check this thread for information regarding the switch to RBG LED's with a controller.

**** Update 5! And we are live!

That's awesome,
They look great.

I would be interested in seeing how much you would make and sell them for. Ill keep watch on this thread. :D

Sweet man! Like omelet, I also would like blue ones to match my blue engine components! Do you have an estimated price?

Jeepforthewin 02-25-2013 09:14 PM

I would Definitely buy these if you started making them!

Omelet 02-25-2013 09:26 PM

Very Nice! As I said before, if you made a set in blue I will buy them :thumbsup:

Omelet 02-25-2013 09:34 PM

BTW the stock dash lights are more of an aqua than a blue or green. I know they make LEDs in the color you would need to match.

craigbru 02-25-2013 10:24 PM

You are right, they are a bit more aqua than anything.

We'll see how my color tests go before I commit to anything, but doing some quick math, I figure I could do $25 shipped anywhere in the US. I have no idea if that is reasonable or not, but that allows for materials and any of my labor/time. Thoughts?

sixfoot9psu 02-25-2013 10:31 PM

Great price!

clbailey 02-25-2013 10:44 PM

Fair price. color options would be awesome, but probably more time intensive.

Omelet 02-25-2013 11:09 PM

Sounds like a good price to me! I'll pay it for sure!

punisher65 02-25-2013 11:33 PM

Those look awesome! Also I see you did what I have been thinking of doing for a few weeks now...carbon fiber wrap over all the wood trim stuff. I assume it wasn't too hard? Anyway, good work!

I'd go for a set as well, would prefer a white color to match my led interior bulbs.

moonvan 02-26-2013 12:35 AM

sounds like a good price point to me.

GregB_00XJ 02-26-2013 01:05 AM

I to would be interested in a set to match the interior lights (aqua as mentioned).

$25 bucks sounds fair to me!

Very cool mod!!! What colors can you do them in??

The time now is 10:59 AM.
