The panels and warning lights in the Mi-24 are slowly being replaced with English panels. The initial work went pretty quickly, but some of the panels are very difficult. It took several hours to remove all the "jewelry" from the front of the Fuel Systems panel in order to update it.
We use 20mil Lexan stickers that have been engraved from the back. Once the stickers are in place they stick like Grim Death, so its important to get the placement just right. The resulting panel has an almost identical look and feel.
Here is a circuit breaker panel next to the original for comparison.
