Ill start off with the pics

I went with the LED idea because the hyper white bulbs i was using up front
kept getting so hot because hyper white bulbs burn hotter and melt away the
plastic clear marker literally over time. LEDs produce no heat and are
very effective and longer lasting.

I used to have a huge DIY with pics on how to do this but I guess it got
lost. Anyways, I will put this together for you. If you have any other
questions feel free to ask.

That is the LED I used. I got them from VARAD lighting products and I got
the white ones that do have a bluish tint to them because they are LED.
(kinda like an HID headlight.) Here is a list of tools.

SUPPLIES:
-4 VARAD LEDs (your color choice)
-18 Gauge black/red wiring
-RTV clear silicone
-Epoxy
-(2) sets of Saturn SL 91-95 clear front sidemarkers
-Wire Strippers
-Wire Cutters
-Soldering Iron
-Solder
-9 Volt Battery
-Crimp tubes

How To:

1) Take your rear sidemarkers (the red reflector ones) and you will notice
they are shorter than the clear ones. Easy fix, measure the length of the
red ones and hack off the tail section of the clear one, dont worry you can
seal it up easily.

2) Place a small bead of RTV clear silicone into the space, just enough to
fill the hole and not too much more. Then once the silicone is dry, you
can put a small thin layer of epoxy over the siliconed opening, this will
make a perfect seal from any elements garuanteed.

3) Now you will notice that the LEDs are a) long and b) won't fit into the
sidemarker holes. Simple fix, just somewhat time consuming. Take the
soldering iron and let it heat up and place it on the inside of the
sidemarker sleeve for the bulb. Melt away a portion of the side and do the
same for the portion directly across. Seeing as the LED has a little
square plastic transformer it needs to slide into the sleeve to fit. Once
again an easy fix if you melt off some of the sides in certain spots for it
to fit, it also helps create a snug fit for the LED.

4) Now the length issue. the black hard wires going from the transformer
to the LED are a bit long, by like a small fraction. Determine how much to
cut off, and seriously clip them and resolder back in place, very easy if
you know how to solder, its a small piece to work with but you have to do
this for all four if you want it to work right.

5) Now that you have the markers and LEDs almost set to go in, you need to do the test to make sure the LEDs work fine. Just connect the loose red and black wires to the 9-volt battery to see if they light up, if they do your golden.

6) OK, you must now seal the LEDs into the clear markers. Just slide the plastic transformer from the LED into the soldered slots you made and once in place take your RTV silivone and fill the sleeve. You don't need a lot just enough to fill the opening and a bit deeper to make sure it is sealed from the elements. Once that dries you can install them, so hang out and let them seal. Silicone takes a few hours to set perfectly so you can moves stuff around without damaging it so take your time and be patient, this project took me about 4-days to finish working spuratically at it.

7) Wiring your LEDs into place is simple. The front ones are a bit tricky, but again fairly easy. If you want them to flash intermittently with your parking lights like I did, great effect and highly recommended. Your front sidemarkers are powered by a brown and black wire. The brown is the positive. So take the brown wire and connect it to the positive (red) wire on the LED. The black wire can hang since you wont need it and you will see why. So it may be clipped back and hidden back in the slot of the bumper. Take the blue wire from your parking/turn signal lights and cut it. Strip the ends and get your 18G wire (only need one wire) that you got from Radio Shack.

Now crimp the blue wires back together but make sure one of the wires from the 18G is inside of one of the crimps for the connetion ( I drew a few pictures on Paint to show you the wiring setup at the end of this DIY.) Now run that wire down to where your LED sidemarker is and run it along the side of the engine bay to keep it from getting caught anywhere. Once it is down there crimp that wire to the black wire coming from the LED. That is the ground but since you connected it to the flasher wire on the parking/turn signals it will now flash intermittently and stay on with your parking lights (cool trick.)

9) The rear marker needs to be lit up now. So pop off your rear taillamp, simple with a hex driver I believe (it's been awhile) and you will see where all the lamp bulbs are connected. On the taillight there is one bulb on the very edge that is a 194 size bulb (small). Simply cut the wires going to that bulb (but leave the bulb in so the lamp is still sealed from the elements.) and connect two strands of the 18G wire to those. Run them down to the rear sidemarker and connect. (I am pretty sure its the same brown=power, black=ground for them as well.)

10) Now screw the sidemarkers back into place and your done, enjoy your lights, I did.

If you want me to do the soldering and basic hookup of the sidemarkers themselves then I have no problem with that, alls you will have to do is wire them to your car. I would only ask that you send me the parts (LEDs, Sidemarkers) and I would do the rest. You would pay for the shipping as well and you would get in return the sidemarkers all ready to be wired up and your done.
