Quote: Caught it right in the driver's side bumper cavety at around 100mph. Made a real mess...bird slop all over the inside of my bumper. My thoughts of turning these caveties into ram-air ducts were promptly dismissed...

Cavity Cavities
pancaked a birdie @ 100 mph?. and you didn't crash?.. hmmm.. you must be pretty amazing driver.
Ram air?.. for what the brakes? or air intake.. no point in doing that.
having an ugly ( my opinion) set of F.U. lights as accessories on your front end is asking for trouble, you never know when that trucker you just toasted with your super brights will make a U-turn chase you down and activate your dental plan.
a better way to handle people who use their high beams ( usually people who can't see all that well, like old folks... excersize some compassion maybe?) is to politely flick them back with your brights.
