Gaffer's tape big claim to fame is that while it is sticky as all-get-out, it will peel off without damaging what it's stuck to. You still have to be careful but unlike many tapes that are designed to be permanent, Gaffer's Tape is designed to be temporary.
I get mine from Summit Racing, but it's widely available if you know what to ask for...
My two favorite flashlights are the FourSevens QP2L-X which can go from a night-vision-preserving glow to 480 Lumen searchlight (for the Gen-2 model). This uses Lithium 123 batteries which will cost a fortune at someplace like Lowe's or Staples but are available cheaply in bulk if you shop around. Their shelf life is measured in years... Shirt-pocket small too.
Slightly larger is the LEDLenser T7 or the almost identical P7. 3 brightness settings, adjustable beamspread from broad to tight focus. This takes AAA's you can get anywhere.
I'd also suggest a pad of Post-It's and a Sharpie.
