This lamp..and this remote control... and thats all i need
But like many above said.. it all depends on location.. I take a heavy kit with me since a lot of mine are out in the woods hikes and I travel solo most days.. so if the worst case would happen.. slip, fall, twist an ankle break a limb.. I have supplies to survive overnight, and keep me entertained till help arrives..
If its an urban one, gps , pen and a couple items stuffed in the pocket are fine...but the rest of the kit is handy in the car
