My LED Tail Light Project

Recommended Posts

Well here it is! Inspired by Derek (D_Venable)

Still a LOT of work to do but I am getting there slowly

The pcb strips are from lunaraccents.com LEDs are 3mm 6000 MCD white from Ebay .. scary I know, but much cheaper

The strips are able to be cut into any length at 1.8 inch intervals. Very happy with them.

I'll be sure to update as I make progress

 

After a few days of long hours I got 4 of the strips populated ... hmm ... looks like this strip has one in backwards. 288 LEDs 142 resistors installed and only one backwards ... I can live with that. Easy fix

Video clip making sure they all light

Got one of the tails apart!

One UGLY Cracked lens .. I will get some new tails once I figure out everything with ones I don't care about destroying.

And Finally a test run trying to see how it's all going to work and look behind the red lens. Parking lights, brakes, then turn signal

I may end up putting 2 rows of LEDs together for each one you see in the video. That's still up in the air.

 

ok finally got around to getting some pics up of my new setup. I know the car is filthy and in desperate need of a paint job. What can i say .. 6 years in a barn and dirt roads aren't friendly. I am also aware the the pass side pipe hangs about an inch lower. Gotta love the local shop. Check out the rear end though, One day soon she will relive her former glory :)

Anyways here they are

Backup lights. Waited too long for this one and it got dark on me. I blame St. Patrick

short video, parking lights with 4-ways, without brakes, prop rod was giving me issues so I wansn't able to get a pic with all 3 sets lit. But you get the picture

lookin pretty good! how do you take the tail lights apart? is it hard? i wanna experiment with taking the colored lenses out and stuff

It's not bad at all to get the lights apart. I just used a heat gun and went around the edges from the back side while slowly pulling the front lens off.

The only problem is making sure you don't get a spot to hot and warp it. That's why i am practicing with my beat up lights.

Yeah the strips worked out very well so far. I am definitely going to put 2 sets of 2 rows because I don't think the single is bright enough and I have plenty of pcb and LEDs left yet.

Hopefully tomorrow i will get some more progress and get them test fitted on the car.

 

Edit:

Just got my car out this morning for it's first run since fall ... without tail lights ;)

Now that it's getting warm enough for the roads to be half way decent and record highs scheduled for tomorrow I am sure that will motivate me to get these done ASAP!

so after you split the lights apart, do need to reglue them before final remounting??

 

Graham

 

YES you do.

 

BUT I recommend getting some silicone sealant/glue, or clear silicone RTV (can find any/either of them at either your auto parts store, or places like home depot/lowes/walmart with all the other glues/epoxies)

 

Using the silicone will seal them back up, yet remain flexible and allow you to easily pull them back apart again if you decide to change your setup.

I was wondering about the best way to seal them back up. There is quite a bit of glue left in the rear of the light assembly so I may have to hit it with a heat gun to get it back flush.

 

If all goes well I may have them done tonight!

Well I took a video of them in the car but my cable for the camera is missing ...

 

Anyways i have a question for you D. How did you wire them to the car? I'm a little confused with only 3 wires plus a ground as to how I get 4 functions from it. I remember that you added an extra pin in to the connector, but can't seem to find it as I look through your post.

Could you give me a little more details please?

I used extra pins out of a spare set of stock connectors I have.

 

But you have to separate the brake and turn signals. this requires cutting a wire up at the fog light switch plug under the gauge cluster hood (can be found on this site)

 

From there you have to run a new signal for the brake off the 3rd brake light. you can tap into that on the driver's side hatch strut. (also found in above site)

I have my LED tails all done and installed, with crappy cracked lenses .. Took some pics/video but I can't find the damn cable to get them from the camera to the comp. When I do I will be sure to update this post.
