Must be due to the neon lighting. Same type of light that hotels and detectives use to see if semen or and other body fluid residue is left on beds or furniture

^its not neon, its ultraviolet light that the detectives use to detect bloodstains and identify genuine cash from fake. Neon is mostly used as fluorecent light, simply an attractive lamp.

^^also known as "blacklight", though it's probably worth noting that in older contexts - for example WW2 and early Cold War era night vision gear - that term referred to active infrared illumination which is right at the other side of the visible-light spectrum.
Funfact about UV - while mammals have categorically lost the ability to directly perceive it likely thanks to millions of years spent as small nocturnal critters (not much of the stuff available at night) dodging dinosaurs, it's ubiquitous among eg. day birds (night birds tend to lose it for the same reasons mammalian ancestors did) and many invertebrates. For example birds of prey can locate little rodents from the fluorescence of their pee on those wavelengths (a trick adopted by human pest control workers), and many a drab-looking plumage, exoskeleton or flower looks spectacularly different if your eyes have the pigments needed to pick it up.
Incidentally on quick parse it seemed to me neon lights are one of the relatively few commonly-used light sources that can't be adapted for UV :P

Actually, that's not entirely true. We still have some ability to see light at the edge of the UV spectrum, but you usually need something to help filter out the normal light to make it more visible.
