If you’re going to be wandering through test chambers all alone, you’re going to want to have a companion, right? While you could go with an ordinary Weighted Companion Cube, why not get one that lights up, just in case the lights go out?

This cute little Companion Cube will accompany you through the darkest of nights, and it will never threaten to stab you. This 2-inch aluminum and plexiglas cube is made by Nathan Van Kampen, and is guaranteed to illuminate – at least until you toss it into a fire to be euthanized.

It measures approximately 2″ x 2″ x 2″, and is lit by an LED and a coin-cell battery inside. You can grab your own Lighted Companion Cube over on Etsy for $15(USD). Just don’t let GLaDOS see you walking around with it.
