Led Fogs

My quick review You will notice that your pattern is pretty much cone shaped. You really have no need to light up the sky or the ground, but you do have a need for lighting more to the sides. Some sort of optics are going to be needed. I would probably have the top and bottom straightened out for a brighter on-axis display. Then you would want to broaden out the sides for better off-axis lighting. Another option would be not to use a flat circuit board, and use something with some complex curves to distribute the light better, like the shape of the reflector in a fog lamp- but a little flatter Make sure they are good and visible- 500' is the standard that most states use, but that is pretty weak IMO. My concern would be of liability. Even if they are visible; they are not SAE approved, and therefore illegal. Get into an accident and it is your fault, and remember this: 7% of firefighters killed in '04 were responding in their POVs to the scene or station. IMHO, you aren't going to save much in the long run, if any. And the couple of dollars you may save are not worth the risk. Get a set of halogen pedestal mounts if you want physically large lamps, or some TIR3-sized lights if you want the low current of LEDs. The Lightning LED LX4 costs under $70 in any color combination, and the 4 Gen-3 LEDs already have the optix and testing behind them

I'l have something in a day or so. I'm away from my regular computer right now.

about those luxeons, you dont have to have a constant current regulator do you?

From what I have read and been told yes, you will need a constant current reg.

it says in the manual, found here ( http://lumileds.com/pdfs/AB11.PDF) that you can use resistors and any voltage
