Light sources for PP3/9V batteries
			 
			 
			
		
		
		
			
			I'm writing a story and in it I mention that the light at the end of the tunnel when you die is actually a flashlight that takes nine-volt batteries. Is there any light source in the real-world I could use instead? My dialog is below: 
 
I asked her as the train rattled on through the darkness outside, asked her what was behind the light. 
 
“A big hand holding a flashlight,” She said with a laugh, and her nose crinkled with her happiness, “A big blue flashlight that, curiously enough, takes nine-volts.” 
 
“Really now,” I commented interestedly.
