Many thanks for all the suggestions! Here's what I finally managed to fit in that flashlight:

• 2 Micropur pills
• 1 flat match
• 1 needle
• 1 striking surface
  

I'm not sure if the Micropur pills will stay good especially with the occasional extra warmth from the xenon bulb, but perhaps they are still better than nothing.

I also filed down a standard flint rod to make it fit in the cigarette case. The file section of the credit card sized multitool makes an excellent striker.
