timing light Q

[AdrenalineS14]

hey guys this is prob a stupid Q but just wondering can i hook up a timing light to a separate battery like say another car... reason why i ask is cause my battery is relocated to the trunk i know i could prob just find a 12v hot wire for power but my other car is like a foot away from the car im gonna be timing and the other cars battery is right there cause the hoods always up lol

thanks for your input guys:o
