No, the only distress "light" that meets requirements is a special one which flashes SOS automatically when turned on. The only company I know of that still makes one is ACR. The problem with the light is that it just may not get that much attention. http://www.shipstore.com/SS/HTML/ACR/ACR1842.html The flag DOES meet the daytime requirement, but in my opinion is a joke. How much attention do you think that will get? Most boaters probably wouldn't even know what it signified. If you're REALLY in trouble, you'll *want* flares, rockets, grenades and whatever else. So choose wisely. I went through a similar thought as you about these - except in my case I didn't like having the highly flammable and potentially dangerous flares on board. However, after watching these videos, I changed my mind. I decided to go with orange smoke for daytime and meteor flares for at night. Yeah, like flares they still expire 42 months from manufacture, but they WILL get attention and at least they seem a lot less hazardous to use than flares. http://www.boatus.com/foundation/Findings/...ngs45/page1.asp The Personal Marker Lights are not a requirement for non-commercial boating - though very much recommended that you have one on your lifejacket.
