Make sure you drill the hole in the bottom of the strobe if it is to be mounted on the bottom of aircraft. I made the mistake of not drilling and had to buy a new one due to water collecting in the unit.

Whelen lighting products are good quality but grossly overpriced. And in the last 2 or 3 years the prices of many of their things like LED beacons have increased 30% or more.
