Ok, anyway I believe 3 is not enough. But my choice would be:
1) multitool;
2) Bic lighter (better than a torch for light, and for high altitude/wet conditions firemaking);
3) Smartphone. In addition some modern smartphones have a very bright screens, which often works much better than your average single AAA flashlight, and some have UB LED flash for the camera, which could be programmed to go off continuously. Advanced models may have standalone FM Radio module built in and a regular GPS unit/compass. Throw in a plastic belt holster (or resin skin) and you've got plenty of tinder too

Seriously, the number of items means nothing. The weight and volume does. What can prevent me from stowing a couple of scalpel blades behind the phone's battery door for example? Limit of 3 items per household?
