Gear indicator lights

[Rick G]

I'm looking for spare "three greens" lights. I have one bulb burned out. I was looking to replace the bulb and also have a spare to keep in the glove box. (it's pretty annoying having to swap them). Looking for part numbers for both the bulbs and the green covers. (I'm assuming I can pull the bulb out and replace separately?) Has anyone replaced these with LEDs? 77 Lance 12V.

Thanks
