Cooldac LED Lighting Kit for Lego Sets

Got this Cooldac LED lighting kit for Lego sets. It's still in the original plastic wrap, never opened. The box says it's for a specific set but the label is a bit covered, looks like it's for one of the larger builds. Great if you want to add some glow to your Lego display without spending a fortune on the official stuff. Box is in good shape, just has some price stickers on it.
