The MV brand of lenses are used by many modelers to replace head and tail lights. Sometimes this is as simple as replacing the clear plastic lens cover provided with some kits. Other times, one needs to hollow out the kit headlight with a Dremel. The results are generally worthwhile unless you cover your vehicle with a lot of mud or dust, obscuring the replacement lens.

This is an incomplete list of MV lens numbers for particular kits. Drop me a line if you know of others. MV lenses are sold by many online dealers as well as hobby stores (check the railroad section).
