Glass paint can be purchased from a majority of local hardware stores, mass merchandisers, craft stores and in the craft department of most department stores.

If a person is going to paint a light bulb, it should be thoroughly cleaned and dried so the paint will adhere well. After the light bulb is painted and the paint dries thoroughly, the bulb must be baked in the oven to help set the paint.
