Blue dot tail lights are illegal on U.S. roads because federal law requires rear lamps to emit red light only. The blue insert alters the color, making light emitted more of a purple and conflicts with lighting reserved for law enforcement.
The practice dates back to the early 1900s, when blue dots were used to help identify speeding police cars at night. During Prohibition, bootleggers adopted the look to disguise themselves as law enforcement and evade capture. By the 1930s–40s, hot rodders revived them as a style fad, and even today some muscle car and hot rod enthusiasts still add them for fashion. Interaction with law enforcement remains mixed—some officers ignore them as nostalgic styling, while others issue citations since they remain technically illegal.
The purple effect can be seen in the picture of the taillights when darker. You can see the purple in the right side.
Generally, you would have a glass dot which would sit infront of the bulb. That was not doable, and for above stated legal reasons I resulted in running LED's. I also learned that when I move the car to LED taillights, the blue glass filters the light making it a black hole from the rear. Now with the LED markers in the taillight lenses, I can turn them on and off as wish while still getting the style I am looking for.
It's givin the man the finger. There's your simple, non BS unconvoluted answer. Dang John, make it complicated why dontchya? LOL

Has anyone used or known someone who used stainless steel brake hose with AN-3 fittings in replace of hard lines? If so, how did it turn out? I have a neighbor who says its a bad idea as the hose bulges a little making the brake feel spongy.

if the whole car's plumbed with flexi lines you will notice a softer pedal. i worked at a rally car supplies shop/warehouse and they discouraged customers from using all stainless braided flexi.

Bummer. Its so hard to accept that as some of these lines can sustain 4000 psi as a normal operating level when brake fluid psi is under 1500 psi.
Well, back to hard lines it is. Classic Tube is being difficult right now. And I am looking at other solutions.

i've always cut and flared my own hard lines using pipe on a roll. flaring tools that give nice neat flares are pretty cheap these days as are the fittings and pipe.

First attempt was a failure. I am trying a new flaring tool by Titan. See how that goes. Bought my flexible tube kit from The Stop Shop. This job will be made worst by not being on a lift. We will see how it goes. Stainless an AN-3 fittings would be so much easier.
