I think I will make a thread when I am done with my tail lights. Isn't too hard so far, just takes some time, a lot of thinking, and TONS of creativity. The best way to do this would be to custom mold your own tail light housings out of fiberglass or some other form of ceramic or plastic, but I am getting the same effect out of some common household plastic items to save some money. You will need either individual L.E.D.s and a circuit board to put them in a pattern, or you can do like I did and use some L.E.D. strips that you can get off of eBay.
The strips labeled "5050" are the brightest, but are usually spaced farther apart than the 3000 series lights, which emit less light, but come packet tighter together. You will also want to check how many L.E.D.s are in each strip. Usually they will be sold in lengths of about 15 feet and have either 600 or 300 L.E.D.s within that 15 feet. Usually the 3000s series will come in the 600 per 15 feet string since they can be placed closer together, and the 5050 series will usually come in a string of 300 per 15 feet due to their increased heat output (Which is still less than a regular or halogen bulb).
Then you just have to decide on a design, and find some way of mounting that design so a mold. I am using solid sheets of 1/8th inch acrylic as my backing plate, and another piece as the lens to cover the L.E.D.s when done. Then I will be using tail light tinter to conceal the wiring and molding underneath by tinting the outer panel of acrylic. You can also buy the acrylic in a black color that will still show light through, but as I bought most of my parts online I wasn't sure how dark this would be, and chose to just tint mine myself.
You will also need to have some basic electrical knowledge to wire up some resistors inline with your brake and running light wires before connecting them to your L.E.D.s (I can explain this more in depth later). The purpose of the resistors is to make the L.E.D.s appear dimmer when you want to use them as a running light, and to amp up the flow to make them brighter when you press the brake pedal.
I will make a thread and post pictures as soon as I finish my own lights. Glad to see that my project has some interest. Might be a way to make some money outside of work if people like them. They are relatively cheap to make, so far I am in mine less than $75, and that includes buying a bunch of new wire spools, connectors, electrical tape, a soldering gun, and a bunch of solder (which most people already have). I would say if you already have the tools you could make these lights for around $50 and have lots of left-over L.E.D.s and wiring material.
