Swimming safe at night in open water. Suggestions?

Hi guys! Does anyone swim at night in open water? Sometimes I swim at night or at dusk in the lake. I don’t care if it’s day or night, I’m not scared of darkness, but I’m sometimes scared of boats that ride preeeeetty fast… I worry that someone might not see me swimming and ride over me…:afraid::toohurt: Does anyone have tips how to stay safe? I made a research and found few lights that might help make myself visible for others on the lake :whiteflag:. First one is safe light by Petzl. I could strap that light to my hands. You can look at it here: www.night-gear.com/.../Detail.bok . It’s waterproof to 3 feet. Second one is a headlamp by Petzl (Petzl eLite). It’s a waterproof headlamp that can work as a flashlight and as an emergency light. It looks pretty cool. You can look at it here: www.night-gear.com/.../eLite-by-Petzl.htm . It's also waterproof to 3 feet. And the last one is a scuba strobe, or emergency strobe. I think this one might work really well, but I’m not sure if there any restrictions in using light like that in non-emergency situations. Does anyone know about this????? You can look at that strobe and how it works in youtube here: www.youtube.com/watch - Scuba strobe test Any suggestions will be appreciated! P.S. I’m not trying to advertise any products or websites. I’m only looking for answers and maybe my post also will help someone who has the same problem as I do.
