Visibility hack for your furry pet during night camping

I usually let Sisi stroll around camp grounds "off-leash" if it is allowed everytime we go camping. When nightime comes, it is hard for me to see where she is, so I thought of putting a head lamp that serves as a second collar to her neck. In this way, I can easily see and locate where she is, especially when she gets far away as long as the headlamp is lighted. It also illuminates her pathway and makes her visible even in the darkest areas of the camp.
Tip: Consider a splash or waterproof device when your pet likes going to the wet part of the camp. Also, make sure your devices have sufficient power.
