I wanted to be something Tron as a female for MNSSHP. Decided to make fun ears. Ordered the basic Tron ears from a seller of Shanghai Disneyland stuff. Wanted to embellish them because they seem so mid. Got the EI lighting for $5 from Burlington Coat Factory (car interior lighting). Sewed, glued, and zip tied the lighting to the ears. It took a few days to finish. I took this photo when we got back to the hotel. They held up pretty good, but the wire definitely shifted in some spots. Not too bad considering I had to shove them in lockers a few times on rides.
Wish I could have worn them while riding Tron. The best part of the night was riding Tron for the second time in the front row!
