The other main function of the utility belt is to house the Spider-Signal. Unlike the call-to-action Bat-Signal, the Spider-Signal is a light contained in Spidey's belt that projects an image of Spider-Man's mask. It's mostly used to announce his arrival or intimidate criminals, but it can be used as a flashlight when Peter finds himself having to navigate dark areas like the sewers. In Amazing Spider-Man #675, Peter updates the Spider-Signal with a UV light to scan crime scenes for forensic evidence. Despite five solo movies, the Spider-Signal hadn't made a big-screen appearance until the post-credits scene for Captain America: Civil War, which showed Peter discovering it in the web-shooters Stark had made for him.
