Hello. I am working on replacing some of my interior lights in my car. I have been reading up and came up with a schematic. I am going to be running 6 LEDs in parallel. I used a resistor calculator and it said to use a 82ohm, 1W resistor. The LED specs: forward voltage is 3.2V and the LED current is 20mA. I know I can buy lights but I like doing it myself. I have read that the LM7317 is used because of DC's regulating voltage. Let me know if I have anything wrong and how I can fix it please. Here is a link to the picture, since I couldn't scale it down, of the schematic: http://moonjob.googlepages.com/12vMapLED.JPG
