I was wondering if anyone has come across an SOS Signal Light
appropriate for kayaking and one that meets USCG Regulations regarding
visual distress signals?

I am aware of the ACR Electronics DistressS.O.S light, but this light
seems quite bulky and I would like something easily attachable to my
PFD.

The VIP Signal Light would comes close, but apparently does not meet
USCG regulations regarding visual distress signals.
