I had a friend in Lubbock who had bought a TwinSonic that came with red domes. He ran a service that did roadside assistance and couldn't have red to the front but could have red to the rear. Blue or amber forward was o.k., so he got a blue dome and took it and the red dome to a plastics manufacturer in Lubbock and they were able to cut both domes and put them back together with blue to the front and red to the rear. Seems like they used some kind of clear silicone in the process.How are the dome halves attached? Glue or some type of plastic welding process?
That reminds me of an ambulance I used to see as a little kid. It was a '51 Chevy sedan-delivery. It had two clear driving lights mounted on the front corners of the roof which were painted red. The only "real" red light on the ambulance was the spinning PropelloRay light on the fender-mounted siren. It belonged to Ellis Funeral Home here originally, and when it was replaced by a '54 Ford wagon, the Chevy was given to the predominantly black funeral home. Something you'd like, Dan, a red BR2 was added to the rear roof, but the nice big siren/light was replaced with a tiny Federal VL siren. The guy just couldn't understand why people weren't seeing and hearing him!You are correct, it was terrible.
