Here's a short video of the dimming. It's a little glitchy simply due to the crusty nature of the potentiometer in the headlight switch, but overall much better than stock.

The dimmer puts out about 9.3V to 11V, and the Arduino code looks at that range and brightens or dims the LEDs proportionally via pulse width modulation. Generally, if you use LEDs inserted in place of the standard dash light bulbs they won't dim correctly, as the voltage range coming from the dimmer is just too narrow to make a visible difference, so you end up with just on or off pretty much.
