Wow, on the older version of the BAndit, I have the Clear Alternatives tail light, and it has an inner molded red lens, so you can use a normal bulb.
I didn't know the version for the newer bandits was different.
You might check a larger autoparts store, like in the metropolitan area of Wichita Falls, (Been to Burkburnett!!) anc check for red tinted bulbs.
You might also be able to use some of that red lens repair tape. What is the number of the bulb? Advance, or Autozone may have them in tinted versions.....or J C Whitney.
