This is a Vintage Green Glass Light bulb lot. I don't know exactly what these were used for so I'm leaving that up to you, I thought they might be used for a Rat Rod or Rat Bike project. Be sure to read all condition descriptions. The pictures are a substantial part of the description so please examine all the photos and contact me if you have any questions. We will be happy to save you shipping costs by picking this up at our shop. Thanks for looking. 092421-RK-04
