Going to concert without lightstick?

Edit: Solved, thank you!

Hi, how frowned upon is it to go to a concert if you don't have a lightstick? I want to go see Dreamcatcher in November but lightsticks are sold out everywhere. I'm wondering if there's a generic lightstick you recommend getting or if I should just go without? Will people think I'm being a jerk, etc? This is only the 2nd full length show I have the chance to go to and I already stand out bc I'm an older fan. I just want to make sure it's fun.
