Sorry for the cross-post, but someone was asking about Daytime Running Lights (DRLs) in the Model S forum and I mentioned the Model X DRLs in a reply there, but I feel it bears a topic in this forum.
Remember the glowing suits in Tron: Legacy? They were built with a relatively new technology called Light Tape where the entire surface of the tape (safe for a tiny border used to seal in the phosphors) glows with a very uniform and bright light. They are incredibly efficient for the amount of light they produce.
Well, the DRL strip on the Model X prototype is made of Light Tape. You can see this on the Model X page in the "click and drag" falcon door picture. The Model S with a less advanced DRL strip made up of individual LEDs behind a diffusing lens and the Model X with its Light Tape DRL strips both have their DRLs (and their headlights) on right next to each other for comparison. It's hard to tell from that one photo just how much light they are putting out, but they are certainly noticeable in the picture and easy on the eyes compared to the glaring of the other light sources shown.
One more cool unhyped detail awaiting Tesla drivers...
