Well, they're actually *for* cycling, right?
(I am afraid of anything PT says is only "water resistant")
I don't know...the Corona is only water-resistant (waterproof rating level 1, "water resistance to splashing and quick dunkings"), and they seem to be better with water than the Apex (waterproof rating level 2, "waterproof integrity down to 1 meter for up to 30 minutes").
I would imagine that a light designed for cycling would be very water resistant, because in the colder months it's *saltwater* that has to be resisted. (There is a version of the Corona for biking.)
I tried using a Petzl Tactikka Plus as a bike light once...it lasted three days (of about an hour of biking each day) and even after I managed to get the corrosion out, it still had the problem where you press the button ten or twenty times to turn it on or off, or just wait and it turns itself on and off, and it has one mode which is "dim and somewhat flickery."
I brought it back to the EMS where I had purchased it and explained to them what I had done and they said, "yeah don't do that" and let me exchange it for a new light.
