Reddit mentions of Wireless Endoscope, ROTEK Semi-rigid WiFi Inspection Camera IP68 Waterproof Borescope 2.0 Megapixels 1080P FHD Snake Camera with 8 LEDs Light Compatible for iPhone iPad Android Phone, Tablet PC-16.4FT

For a right angle 18650 light, I'd recommend either the Skilhunt H03 or the Armytek Elf C2 warm. Both lights share the following:

• Magnetic tail with tailstand
  
  
• Warm or neutral tint
  
  
• Around 1" head
  
  
• Water resistant
  
  If you're looking to see what's behind your walls, I'd suggest something completely different. Get a borescope with LEDs on the end, there's cheap ones on Amazon that work either with or without a phone and have decent reviews, as well as brand name options. The pictures won't be as good, but you can use much smaller holes and you won't have to worry about dropping something into the wall. Often you can go down into the basement and drill up between the studs instead of having to put a hole in the drywall - no patch work necessary.

If it is located could put some tape, sticky side out, and then maybe be able to snatch the card.
