Cyclotron Lights-Refelctors?

What is used for the red part of Cyclotron? Is it a reflector? would I be alright getting some of that red tape used for tail-light repair? This is my very first build, and I’m starting very cheap (tight tight budget). I just want to be a ghostbuster for Halloween this year and didn’t want to pay the 45 dollars for the cheap blowup proton pack one at Walmart. any help would be much appreciated.

you can use red acrylic, or red light color gel.

The originals did not have any reflectors on the inside, but some builders do opt to have them to increase brightness.
