Highlights in a man's hair that is wholly unattractive: generally an indicator of one's toolish nature. Look for a pompous air and cheesy smile. Guylights are perhaps a descendant of the late 90s tendency to bleach one's hair until it looked like a skunk had pissed on it.
Barbara: Suzy, what do you think of him over there?
Suzy: With the technicolor hair? I could never date a man with guylights, Barb.

a 2010 parody film of the popular Twilight franchise made by two high school seniors at Los Altos High. Unfortunately, the movie was never finished and the project considered a failure after everyone was totally stoked to see it. Basically imagine them canceling the next Batman movie...
Dude I'm so fucking bummed Guylight didn't get finished before the film festival.
