Upgrading 1965 Barracuda brake lights

Not to take anything away from making your '65 Valiants into modern cars, but I have found if you put aluminum foil behind the bulb glued to the base to reflect the light better it brightens the bulb enough. I had to do that on a '75 Dart to be able to see the brake light.

I amnot sure if this is allowed but I sell the lenses for the '64, '65 and '66 Valinats. They are driver quality but not for 100 point resturations.
