Let it shine wherever you go
Let it make a happy glow
For all the world to see"
- Sailor Moon's final form consists of her having wings and a Glowing lotus symbol on her chest.
- Iron Man's power source resembles one of these.
- The circles on the armor of The Mighty Thor are sometimes portrayed as glowing.
- The post-Annihilation costume of Nova has these all over the place.
- As shown in the page image, the Alpha Lantern Corps makes use of these. Most of them are both aliens and robots/cyborgs.
- The Green Lanterns themselves sometimes employ this when the lantern symbol on their costumes light up.
- ET has the organic variant, and is probably the Trope Codifier.
- In all versions of Iron Man, the power source of the suit is the same as the magnet keeping the shrapnel out of his heart. In the film version, and most animated versions that came after the first film, the "arc reactor" in Tony Stark's chest always generates a light that can be seen through his shirt.
- In Ra One, both (video-game escapee) villain and hero have these. For additional points, the villain's (red-glowing light) is in the center of his chest, while the hero's blue light is off-center, on the left.
- Ultra Series: Ultraman, no matter the incarnation, always has one of these. The faster it's flashing, the closer he is to running out of power.
Narrator, Once per Episode: "The energy Ultraman receives from the sun diminishes rapidly in Earth's atmosphere. The warning light begins to blink! If it should stop, Ultraman will never rise again!"
- The symbol on Captain Planet's chest.
