I just bought a LED to light up a chrome statuette hood ornament from a
1940's vehicle (I think it was a LeSalle?) that is this winged flying
woman of <ahem> slender build... there is a square opening in the back
where I am going to put that LED and put some red plastic to close the
opening. Then I'll wire it to my brights to remind me that I have them
on. It's classier than some old bull horns mounted up front, I think. 

What would be really cool is to mount a weather proof speaker under the
hood and have the "Flight of the Valkyries" play for 10 seconds when I
hit the brights and have the LED pulse with the amplitude. If I could
teach Murphy, my co-pilot chocolate lab, to howl out the window at the
same time, how cool would that be?? Answer: ICE COLD! <cackles> 

It gets really boring out here at the Happy Farm.  Ric
