Skyline Tail Lights (How-to)

So I finished up my skyline style tail lights, here's the how-to for people who feel adventurous. I'm not sure if I'm gonna make these for people yet because they where a real pain, but a lot of that hassle was figuring out all this crap. Either way, I need a break lol... So, I tried to give this all the basic details, but if you can improve on the design by all means go for it. A word of warning: I'm not an electrician or mechanic, so anything I'm saying here should be taken with a grain of salt. If you ruin your car, you ruined your car not me.

-------------------How-To---------------------
Parts!


2x 100mm LED rings, you can find these on eBay if you search for "100mm angel eyes" they comes up for about $20 shipped.
2x 120mm LED rings, eBay got those also.
2x 5 Post relays, I got these on eBay also.
2x PWM's, it's basically a fancy dimmer switch. I got mine from here
You're also gonna need some wire, a few basic tools like a solder iron, wire cutters, a hair drier, a few quick release tabs, and a hot glue gun.
Finally you're gonna need a 32oz Gatorade bottle and a plastic cup.


*BUILDING THE HOUSINGS!*

Step 1: Bake open your tail lights, I used a hair drier... it took awhile but i got them open. I used a hair drier, heated up the sides and ran a knife around the edges.
Step 2: Take the LED rings and center them as best as you can in the housing.

Step 3: (center tails) youíre gonna wanna make some kinda light shield so the lights donít bleed to much. For the center tails I used the top part of an italian cup (Donít ask how I came up with that idea)

Step 3: (outer tails) For the light shield on these I used a gatorade bottle cut it in half and painted black.



Step 4: Glue everything down, I used hot glue and it seems to be holding up pretty well so far.
Step 5: I took some foam packing paper stuff and cut them to fit in the the center of the outer tails so you donít see all the wires.


Step 6: reseal them bad boys back up.... take a break now, the wiring is hard.


*WIRING!!*

Step 1: Take your 5 pole relay and connect up wires to each pole.

Your relay should now have 5 wires coming out, labeled. 30, 86, 87a, 87, and 85.

Pole 30 should go to your cars tail light ground wire.
Pole 85 should go to PWM + Input
Pole 86 should go to your cars running light tab (which the middle tab)
Pole 87 should go to the LED rings negative wire.
Pole 87a should go to the PWM - Input

Now, the PWM should still have 2 unused plus + and - output, which are going to go to your LED rings.

The PWM is also going to have 2 wires going to the + input, one from the relay and 1 going to your cars tail light break wire (the the tab completely opposite from the ground).

And thatís basically it, install them and youíre done! You can use some load resistors to prevent hyper blink, but thatís up to you.

Sweet! you did an awesome job especially with the bottles and cups to keep the light from bleeding and the packing foam in the center to hide wires. Genius!

PLEASE, if you ever decide to make some more, I will be first to buy. I dont need the inner tails done, i just want my outer tails done that way.

Haha, color me stupid, I didn't even notice that. I don't know why I should even both hiding it, but whatever.

I'm not sure if I'm gonna make these for people yet, it took me over 2 months to gather the parts and wire it all up to the point where I was happy with it and I just need a break from the whole thing. I'll keep you posted if I ever change my mind.
