I needed 24v bulbs to replace my dome light bulbs in my armored car / tank dome light that I bought to install in my M35a2. I went to Orielly's and they would not even attempt to look up anything 24 volt. I was sent to NAPA and the small local shop in Hartwell, GA had a box of about 12 of them on the shelf and sold them individually. They said 24 volt stuff is no problem. Its funny how some people act like you have the plague if you ask about 24 volt stuff and other stores have it right on the shelf.
