First version, otherwise why use 6 resistors instead of one single
lower ohmage one of higher power.


I was trying to roughly calculate the power requirements. You said 600
ohm resistors, correct? The voltage drop on the LED will be minimal when
forward biased or "on", so each branch must be about .02 amps, times six
equals .12 amps, so the power must be about 12v times .12 or about 1.4
watts. Probably a bit more when you factor in the LED drop, whatever it
is. Significantly less than a regular light bulb!

Most LED's are in the 400mw range.


How about the standard 12v bulb used for anchor lights?
