It’s not convenient for regular people like us to call for Batman’s help. You need a high rooftop, then you have to make a large spotlight that will call the Caped Crusader. Then, that spotlight takes a lot of power.
When you need Batman’s help, just turn on the old Bat-Signal and he’ll come running. Don’t have a Bat-Signal handy? You can always build a LEGO version, like this one made by expert brick builder Nathan Sawaya.
I’m not really a comic geek so pardon me if this has been addressed in canon, but I’ve always wondered why only the Gotham PD had a bat signal. Wouldn’t ordinary citizens have a higher chance of actually needing the Batman to protect them from the horrors of Gotham City?
Picture this – you’re being held hostage by an evil, bad-makeup-wearin’ supervillian, but you’re 25 miles away from Gotham City. Normally, you’d be screwed, right? But just then, you reach into your backpack and whip out your own portable Bat Signal, hailing the Dark Knight from across town.
Perfect for closet crime-fighters, this replica Bat Signal will definitely give you extra geek cred the next time your friends come over.
The miniature replica Bat-Signal features a sturdy metal construction and stands about 12-inches tall.
