I bought some orange bulbs, and dabbed them with chrome paint, which is basically just bright silver paint, very lightly. They glow bright orange as they should when on, but when off they remain silver, and the coating of silver is very light, but dark enough to hide the orange when the lights are off.
Make a huge difference during the day.
