Hello, I just read an article on a 1935 Packard 8 convertible sedan, there were pictures of the instrument panel in which I noticed the word "pass" lit up to the right of the fuel gage. Looking at close ups I noticed other words to the right of this. Would someone be able to tell me what the purpose of these lighted words are? I am a nerd for little details like this and am really curious. Thanks Spfan
