This baseball cap has a bright green light in the shamrock of a "Pinch Proof" patch.
The illumination can be turned "on" or "off" from a small battery case on the back of the visor. It's about the size of a quarter and houses a 3 volt, CR2032 battery. A new, easy to install battery, comes with every visor.
And this cap is available in Kelly Green and Pink.
