A bit of trivia is that both silicon and saline after market headlights sink while OEM equipment can be used as floatation devices.

(I saw this on Manswers a TV show dedicated to man answers. They tested all 3 and the OEM ones really do float where as the others don't!)

I learned all I need to know about life by killing smart people and eating their brains.
