Good job
That's a good effort, Since you are running the LEDs off a VARIABLE regulator, a simple addition of a different resistor & switch in the LM317 circuit can dim all the LED'S easily. Alternatively the addition of a transistor switch driven by your headlight power can autodim everything quite nicely.
If u want the schematic I can shell one out for u anytime.
The matter of color is of some importance in the case of nightvision you want RED LED for your dash. Amber ok, NOT green, Blue or White. Dimming will allow the use of those other colors though. The lower the light frequency the less it screws ur nightvision. Thats why ppl who use Blue tinted headlamp blind u compared to yellow tinted lights.
Have u guys noticed that Xtrails now come with amber/red dashboard gauge backlights?
