LED Tail Light How-To.
LED Tail Light How-To.

Outer Tail Light Template
Inner Tail Light Template (Correction: the 4.5" on the upper inner should be 5.5")
How-to:
1) First you need to design a template for the size of your circuit boards. You can open up your tail lights by using a heat gun or baking them in the oven. To bake them pre-heat your oven to 300*, turn it off, and put your lights in on a cookie sheet or piece of cardboard for 10 minutes. I am not responsible if you ruin your tails or burn your house down. You should be able to pry the lens off the housing. Be careful not to make a mess and/or brake the lens. If you have a '97-'99 Maxima and need to keep your tail lights on your car while you work on this project I uploaded my templates to Photobucket (see links). Keep in mind they are how i wanted the boards to fit, you may desire something different.
2) If you do not have fairly good electrical knowledge (amps, volts, ohms, series/parallel, etc.) now would be the time to do some studying.
3) Decide exactly which LED's (I recommend Lumileds SuperFlux) you are going to use and whether or not you are going to regulate the voltage. If you are going to use the car's voltage unregulated, it is usually around 13.6v.
4) Design your array. I used the series/parallel wizard (see links) and LED spec sheet to help with this.
5) Decide what type of circuit board you are going to use. You can use perforated circuit board or you can make your own printed circuit board (or PCB, see links). If you want to make your own PCB there are a few free design programs on the web. I chose to use ExpressPCB (see links). I am now using PCB Artist but I still recommend ExpressPCB for the beginner.
6) Design your board and assemble your board. Make sure to pay attention to the polarity of the components.
7) Now you must mount your boards. I chose to mount them by trimming the stock reflector and using clear RTV silicone.
(8) Install into the housing and seal her back up. I used a heat gun to reheat the OEM sealant but you could use the oven.

because i took this on on a production level some of the materials ar different than what you would use on a custom project. i have literally thousands of dollars into it at this point, but a one off custom project could be done for fairly cheap assuming you have the tools.
i'd just like to note that this is not a complete how-to. it is a work in progress.

the price of the marker/brake board kit is expected to fall around $300.
i'm portotyping a 4 row design this week. whichever looks better will make it into production.

haha why give up all the secrets? I had a few guys ask me to tell them how and I told them hidplanet.com. Giving all the secrets makes them not as hot a commodity haha. I'm glad you switched designs tho. What did you do in between the LEDs? Wire? Nice and clean. Mine are messy on the back.
its a printed circuit board, so theres no wires. my feeling is if someone wants to make their own they'll figure out how, if they don't then they'll buy some. i am prototyping a 4 row design this week.
Let me see if Mike wants to upload them. I personally wont give out progress pics. There is tons of info on www.hidplanet.com/forums if you have the time to look.
my process wouldn't really help the diy'er. all you need to do is understand basic electronics, know/learn how to solder, and have enough mechanical ability to cut and glue. all the info is in the post.
So I hate to bring this back, but I could really use those templates for trying to figure out how many LED's Ill need. OP, if you could relink them or let me know how to get ahold of them, that would be epic. Thanks man.
