I bought a set of ready made blue dot tail light lenses for my 28 model A PU . (Yea I know there not legal in my state ) I installed them today and realized the blue dot is in the brake light section of the lense ( top portion ) so it only illuminates when the brakes are applied . Is this the traditional way there ran ?? I always assumed the blue dot was lite when the tail lights were on ????????? I saw some lenses advertised that actually say STOP in brake section of the light and the dot is on the lower tail light section opposite of about how all the other lenses are sold .
I thought I read that the Blue dot was like a up North states bad weather in 30's from rear to Identification of police ,law-enforcement , emergency equipment from distance. Running Light side . Snow , rain , fog
make your Model A smart....then no more dumb Model A questions The two Model A's I have, that have blue dots, are both in the running light part of the lamp, not on the stop lamp, but they are also later lamp assemblies...I don't know about the actual "A" lamp assemblies.... and blue dots but brake lamp doesn't make sense does it...
I don't think it makes sense but that about how all the one sold are offered from speed way to eBay to moon . Mine are lke these 1928-31 Ford Model A Tail Light Assembly with Blue Dot (mooneyesusa.com) These are the other way around with the do in the running light section but is don't like the amber and the word stop on them 1928 1931 Ford Model A Car 'STOP' Tail Light Lamp Lens w/ BLUE DOT A-13450-SBD | eBay I was wondering what they did in the olden days LOL
Of all of them I've seen, which wasn't in the old days, they are mostly Red while driving, but really go Purple when the brakes are on. We are talking 39s, 40s, and others. They didn't shout pull me over until the brakes lit 'em up.

All I can say is that those damned things are annoying as hell when you have to follow them for a couple hundred miles at night. A buddy I did road trips a lot had them for a while until he followed his car in another car one night.
My Model A had the dots on top. Never had a question from law enforcement. Drove that rod 27 years, 110k miles.
