I was just curious about ya'lls experience with Whelen lights on your
aircraft. The reason I'm asking is that I work at the USA's largest
firetruck manufacturer and I deal with Whelen lights daily. My experience
with Whelen lights on firetrucks is that while they tend to be
technologically advanced and fairly reliable, they also have terrible
problems with water leaking into them. Whelen hasn't figured out how to
make a decent gasket, in my opinion. I was wondering if this is also a
common complaint among aircraft owners.

I've had no problems at all with Whelen strobe lights.

I just purchased one of their new LED (flashing red light) to replace a
Grime's beacon I had on the top of my airplane. However, that has not been
installed long enough to have any data regarding water leakage. Because of
potential leakage, there are different instructions for installation if the
unit is used as a belly light; involving sealing up certain holes in the
body that don't get used.
