Well i tinted my stock taillights. Did it myself & it cost me $20. two coats of vht nightshade & 5 coats of krylon gloss clear, turned out a bit darker than I was wanting them too. They aren't 100% perfect but it saved me some money by doing it myself.
The light still shows through pretty well, but the light output sucked before I tinted them anyways, I may put some leds in.
Also ignore the dirty truck.
