According to the good folks at Hallmark who've had ornaments on display for at least a month now, it's never too early to start planning your impending holiday decor. And that probably includes a tree covered in ornaments, though probably none that celebrate the 1980s as well as these light-up Transformers bulbs.
They're available from ThinkGeek for just $10 each, but since the holidays are all about being friendly and welcoming, it would be a shame to choose the Autobots over the Decepticons. So buy them both, and spread a little goodwill all the way to the farthest reaches of our galaxy. [ThinkGeek]
