Light Cycle 2.0 Glow-Core Wedding Ring
You can't have a TRON Light Cycle (at least not anymore, you could a few years ago) but if you're a good fiance, and show up at the altar on time...or maybe just at all...you can have a Light Cycle 2.0 Glow-Core Wedding Ring. That is, a band that looks like a wheel from the franchise's famous motorbike, right down to its phosphorescent blue core.
Made by Venture Custom Shop, the Light Cycle 2.0 is a combination of carbon fiber and glow-in-the-dark europium. You can choose an orange or green color instead of aqua for the latter, which will also appear as a glowing TRON "square wave" around the ring.
