Lightning Bugs, retail $1.29 (

Last updated 08-29-07

This is a gummy candy that comes in a small (1.41 oz/40g) packet, but what made me purchase it is that the tongs included with the candy have a red LED designed to light the pieces of candy up. The candy itself does not resemble a lightning bug (firefly), but instead, resembles a glow worm.

When you use the tongs to grab one of the gummy "glow worms", a red LED in the tongs causes the candy to glow.

In the second photograph above, the package had already been opened.


The product is almost ready to use as soon as you open the package. Remove the tongs from the clear plastic baggie they come in, and gently pull out & remove the long white tab from the center of the tongs.

From this point, any time you use the tongs to pick up one of the candy glow worms, the candy in the grip of the tongs will glow a fairly bright red. The LED in the tongs will automatically turn off when you release the candy and allow the jaws of the tongs to spring back open.

This appears to be a disposable product.
There is no obvious way to change the batteries; and I don't even know what size/style of cells it uses.

This is a bag of gummy candy with light-up tongs, not a flashlight. So I won't strike the tongs against a steel rod or against the concrete floor of a patio, run over them, try to drown them in the toilet, stomp on them, throw them, bash them open to check them for candiosity (O wait!!! It's sold as a small bag of candy, so this would be pretty pointless), fire them from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a scanner-type device on a platform with a large readout or with a handheld wand; and the cannonada is only used to shoot piņatas to piņata parties away from Piņata Island), send them to the Daystrom Institute for additional analysis, or inflict upon them other "punishments" that flashlights might have inflicted upon them. So this section of the web page will be a lot more bare than the same section of the web page on a page about a flashlight.

The following cautions are on the package:
  • Do not point light into eyes.
  • Do not put tongs into water, as it will damage them.
