I need to learn to type fasterCheck out an office suppy or teacher's store like TAPS (TAPS may be a local store) They should have colored overhead transparencies. You can cut out the correct size. Also, Lee dies come in a clear, plastic, container. Q Beam used to sell a red cover for their spotlights. Blue is good also.
In my Cabela's catalog, they show some flashlights with red/blue/yellow lens cover options. These are LED lights, some fairly strong, like 150 to 300 Lumen rated. That would work out to 250+ yards. Let me know if you want the page number. (catalog is out in the truck right now )We saw four bobcats on Saturday night's hunt, but the white light spooked them. Where can I find red lenses for our nightlights? I've looked in Cabela's.
X2 on the Dykem.You can use Red Dykem (metal layout ink), to coat your lenses. Takes on the average 2 coatings and will not dislodge like a makeshift lense. Also will not warp as some plastic will under the warmth of the light.
Dykem can be found at nearly any supply joint that supports machine shops.
