The Etsy "jelly sheets" linked in the prior post work fine. They are thin, and self-adhesive on one side. The seller offers 3-sheet packs of any single color for $8.95 shipped. I emailed and asked if I could get 2 Cherry Red and 1 Emerald Green and they arranged it for the same price.
I cut new clear base sheets for each lamp out of blister-pack material, and then layered the red and green sheets to get good color density. I went 4 layers for the red, and 5 for the green. I noticed the high beam indicator was slightly faded where it says "BRIGHTS" so I also laid one layer of red on the back of that insert as well.
The rest of the cluster wasn't too bad, and since as-new looks is not required for my truck I've been able to skip a few steps. Should have it completed in a couple of days, or whenever I get around to buying the paint for the 2 needles.
