Now, IMO the stock G50 tail have always looked pretty horrid. So I picked up a spare set from the junkyard for $25
Here's the stock tail light:

Once you have the tail light removed you'll notice a rubber seal that goes around the light, you'll need to carefully remove this:

Once removed you'll have access to 4 clips (two on top 2 on the bottom), and this is where it gets tricky, excuse the flash:

Now, you'll need to stick it in the oven at ~200 degrees on bake for about 5 min. This will help soften the goo holding the lens in the housing. Once nice and warm you'll need a small flat head screw driver and gently depress the locking clip while slowly (and i stress slowly) prying the lens away from the housing. You'll probably need to to reheat a few times to remove it without breaking it, this grey/white goo is not soft like the black goo that seals the housing to the chassis and takes some patience to get the lens free.
Once removed you'll see this:

There are two separate diffusers behind the lens. Be careful not to break these when pulling them out you will need to reuse them after some modifications.

IF YOU DO NOT WANT TO BUILD A LED BOARD AND SIMPLY USE A LED BULB, STOP HERE! Simply leave the diffusers out of the tail lights and press the lens back in! You've got a great updated looking set of tail lights, just be sure to use a VERY Bright led replacement bulb.
Here is what the tail lights look like without the diffusers! Such a huge difference!



I ordered all of the supplies, led's, pcb boards, etc which will hopefully be in by the weekend. I'll update the thread as the project progresses!
Ok, finished the pass side rear brake/parking lights, pics as promised!
Here is just the parking lights:

Ok finished up the pass tail light tonight..

Everything On:


I forgot to mention.. here is everything I am using to build these:
Parking Lights = 12k mcd, red, 5mm
Brake Lights = 30k mcd, red, 5mm
Turn Signals = 12k mcd, orange, 5mm
You can use clear as well if your lens is colored, but from what I've read, red leds make the light out put more crisp vs white leds.
Resistor = 330ohm (for 3 leds)
I decided to run these in parallel series (3 leds in series).
Here is what it looks like, however I'm not sure why the resistor is on the - side, it should be on the 12v side.

This website kicks a** and is easy to calculate the correct resistor needed if running multiple leds in series:
