Thanks to Jim B for posting this information on the Yahoo! Loopframe_Guzzi news group. In Jim's own words:
I found some CEV 9350 tail lights for sale new (old stock) at Moped Warehouse. They are old Harley lights in the Harley package likely for the Harley Italian bikes. Price with shipping USD $56.52.
Robert F. Greene sent me the following information via e-mail.
My father replaced the CEV 9313 tail light on his 1973 Eldorado soon after buying the bike new in 1973. He did so for one reason and one reason alone: the original tail lamp just seemed too small to be seen. The replacement was a tail light for a Yamaha, and on my honor, you'd never know that it didn't come on the bike originally, as it complimented the bike perfectly. It is a rectangle shape, and has nearly twice the reflective surface area as the CEV 9313, which means twice as much red brake light directed at those following the bike. Since I followed the bike periodically when he would drop it off for service appointments, the visibility of the Yamaha brake light was quite a bit better than the original.
For Ambo and Eldo owners out there who wouldn't mind a slightly more visible tail light without completely sacrificing an OEM look, a great compromise is the CEV 9350, which was actually original equipment on many 1974 and later Moto Guzzis, including T-3s and Eldorados. My disc Eldorado came with a CEV 9350, and the rare 1975 police Eldos that I have seen were all equipped with 9350s as well. They are not dramatically larger than the old 9313, but the additional surface area of the reflector puts a bit more braking light out there behind you. For the past several weeks, there have been dozens of NOS CEV 9350 tail lights on eBay (not just the lens, but complete units with chrome-finished plastic back) for about $30 plus shipping. The reflector inside my original CEV 9350 was chipped and broken in several places (vibration perhaps?) and rather badly dulled from age, (although the lens cleaned up beautifully with a treatment of 3M Optical Plastic cleaner). I bought a NOS 9350 on eBay. It was a great deal, it looks great on the bike, and assures me of improved brake light visibility.
