the amber is very close to utility flasher yellow (tow trucks, utility workers, etc.), although it may have a touch more orange to it (i've never compared the two side-by-side). order one and check it out.
and, btw, orange and the other red based LSes are more efficient then the whites and other blue based ones. they have a smaller forward voltage drop and, therefore, use less wattage. output of the amber high-dome is twice that of the white low-dome while using less power.
