Good Day All
This thread sparked a memory of an article about the center grille light.
The Dec 1985 issue of the WPC news had a write-up about the 300 L.
The article was written by a Peter F. Madsen and it outlined the trim and running gear of these cars. In the article he wrote: "From personal experience I'd like to comment on several of the trim pieces specific to the 300Ls that cause us problems in keeping up and restoring these last of the letter cars. First I'll mention the notorious 300L emblem on the grille. This little goodie comes equipped with a light that is wired to stay on whenever the ignition is on. The OEM bulbs were tiny little things that all burned out early on in the cars' lives, and most of them were replaced with a slightly larger single-filament light bulb that conveniently fit the socket. Unfortunately, these larger bulbs generate enough heat to crack the clear plastic "L" emblem."
While this doesn't solve the problem, it a least sheds some light as to why they cracked.
I have looked in the service and owners manuals, but have not found a listing as to what number the original bulb was.
If nothing else this is useless trivia.
