Every organization at THON creates spectacular signs to represent their respective organizations. Over the years, light-up letters have taken the spotlight above all. It’s now the norm to flash your color-changing letters at THON to really catch the eyes of dancers, families, and everyone in between.

This year, some organizations shine above the rest, pun intended. Here are our favorite light-up letters of THON 2018:

TETRA’s letters, although they had some interesting spellings earlier in the night, used flashy, pure white letters that blinded their neighbors and caught the eyes of all at the BJC.

Alpha Delta Pi and Theta Delta Chi not only rocked a Monsters, Inc. pattern on their letters, but they both included a flashing, strobe-light trim along the edges. These lights may seem simple and small in the photo, but they haven’t stopped flashing yet.

Delta Chi and Kappa Kappa Gamma used the coolest effects on their letters, hands down. The letters didn’t only have a thin trim along the edges — oh, no — they decided to cover each entire letter with light panels. These panels cycled through green, yellow, and purple lights quickly and beautifully. The letters themselves also have a creative and semi-futuristic design to them along with their lights, making them the most lit letters of THON.

But how do they keep them this lit for the whole weekend? Simple. All it takes to keep these signs flashing their colors is a small battery back attached to the back of the letters and battery replacements every few hours or so.

Keep your eyes peeled for these glowing masterpieces and others if you make your way to THON this weekend.
