The easy-install solution to lighting up awkward lockers and cupboards: a battery-operated LED light with a magnetic switch. Mount the light to the cupboard casing and the small piece of steel to the door (both with double-sided tape, provided). When the door is closed the steel is in contact so the light is off, when it's open the two are separated so it comes on. No wires, no holes! Batteries are included.
