Christmas Parade Float - Theme "Holiday Glow"?

I am a member of my children's elementary school PTO - our school is entering a float in the annual Christmas parade and the theme is "Holiday Glow". We have decided that we are going to incorporate "Rudolph the Red Nosed Reindeer" and have all the children in the float wear red clown noses. The banner at the front of the float will read "Our Future's so Bright, you could even say it Glows!". I am seeking creative decorating ideas for the actual float to incorporate. Thanks!
