Meonum 4 Pack Halloween LED Glowing Light Up Eyes, 24'' Glowing Eyes Lights for Halloween Costume Cosplay, Masks, Skulls, Skeletons and Props, Battery Operated, Steady ON/Flashing Optional (Red)

They do feel pretty cheapy put together, and they aren't the brightest, but should do the job! Comes with a tiny screwdriver to unscrew the battery pack, does not include batteries but takes two AA batteries.

These look really good in skeleton eyes or small pumpkin eyes. When placed in the right position they glow and look lifelike creepy. Sadly there was one set that didn't work. My husband tried to work on it but wasn't able to make it work. The others are good.

As a Halloween Haunter, I'm always doing things the interesting way. I had a couple of older animatronics that did not have light-up eyes and were pretty far from my normal power sources. These little LED power packs work great for one-off needs.I also found that they were great to fit inside one of my large gaming (miniature) Pirate Ships for great, evil Ambient lighting. I have a new project where the LEDs will also be part of double street lamps, with some minor adjustments to the wiring to extend them and better hide the battery pack.As for longevity and power consumption, I've had 1 set on constantly for the past 4 days, with no sign of wearing down.Great little product.

I used these in my skulls for Halloween, they look scarier with the light. These are easy to use and since they are individual pairs, they can be spread out. Good quality.
