if they are weldon, google ambulance parts, found them there for 15, the kansas bus parts place are out and arent getting any more. I found some off an old ambulance, 2 bucks a piece. My local rv place has Amcon lights that are 16.99 for a whole unit. These arent the bus outside lights but the lenses fit. And you have a light you can put somewhere else with a amber cover off the bus, thats what I am doing anyway.
The catalog lists them but the website does not list the covers. W1003C is the cover number. My catalog is in the Jeep and not home. When David gets home (with the Jeep) I will look it up. I did find it at the link below but it was elsewhere. The price (I think) was the same as the Red & Amber covers. http://commerce1.cera.net/tacbusparts/s ... /index.asp
