I can't express just how important it is to have some sort of light when trick or treating. According to every psa leading up to Halloween is that you are completely invisible to drivers. Something about a car windshield makes trick or treaters invisible. Real talk, you need a light.
There's always that flashlight your mom keeps on her nightstand, but don't be ratchet. You need a specific Halloween light. I was always partial to glow sticks, and let me just tell you. You can tie some yarn to that sumbitch and make a necklace. Maybe one of those cool pumpkin flash lights. They do the job pretty well and let you represent properly. Top tier though, is the Pumpkin Light.
A more premium light that as you've noticed has dual uses. Either in place of a candle in your jack o' lantern, or around your neck. A pumpkin shaped medallion that puts off a blinking light ensuring near death by the way of Ford Taurus isn't in your future. The Pumpkin Light is a quality product that's gonna last for years. It's going to sit on your nightstand for awhile before being going in the closet for next year. When you'll buy another anyway.
