Quoted from Travahontas:gto - Arkenstone start button video as promised! This is the 2-inch model. It's REALLY impressive. I added a little wiring mod to mine to make the light pulse instead of blink.

That looks amazing, nice work! Do tell how you wired it up to pulse...I ordered the recessed version of the button and would also like to do this.
