Can we please stop it with sequential turn signals?

Those flashing brake lights are usually a dealer-installed option on new cars. In other words, the cars did not come from the factory that way, but the dealer actually modified the car before sale, which raises some interesting questions about legality, warranties, and automaker permissions.
I know of no instance where a flashing CHMSL is factory-installed.

It was a cheap "safety" add-on that dealers slapped on every car and put on their addendum sheets.

Technically it is not legal. The only lights that are allowed to flash (automatically, without the driver moving the switch back and forth) are turn signals and 4-way blinker.

Flashing brake lights suggest that the pedal is being pressed only very lightly thus there is not an urgent need to slow down.

I am going to go with my hunch that they are against the code in every state. They don’t come on new cars, and very much seem to be the purview of the gang, thug, hood, Fast and Furious crowds.
 
I remember the mid sixties Mercury Cougars having the first sequential turn signals I had ever seen. The Cougar TV commercials at the time likened it to the Cougar twitching its tail. Sequential, red, amber doesn’t bother me at all. What does bother me is seeing the brake lights light up 5 seconds and the driver half way through their turn before the turn signal starts to blink.
Okay, those were cool.
 
What does it say about car culture, when the biggest development that automakers work on for new vehicles is how fancy their decorative LEDs are?
That really seem like a narrow perspective of current automotive development. There is so much going on. After the car company has done everything else, I'm the first to admit that I like a nicely styled car. If not, well, I would just buy a Nissan Cube.

Why are people against the flashing 3rd brake light? Any additional attention I can draw to the fact I am stopped the better to avoid being rear ended.
My complaint with the flashing 3rd brake light is that they really don't do what they are supposed to do. The belief is that by flashing, they get more attention from the driver behind you, in hopes that they will react quicker, to brake. But from what I've read, there is no evidence that they do that.

They cycle at 3 Hz, and are off as much as they are on during that 1 second period. They go off as quick as they come on, and don't come back on for as long as they were on. Thus, they only create uncertainty if the car in front is braking or not, until they come back on the second time. By then, any quick response opportunity has came and gone.

I believe the first application of sequential rear turn signals was on the mid-sixties T-bird. It was cool when it was unique and became less so with more common use. They're everywhere these days.
The problem with the blinking center high mount stop lamp is first, it is not permissible under federal standards, and no state can override that and that the whole notion of some low-level employee hacking into a vehicle's wiring to install the enabling device would disqualify any vehicle from my consideration.
Dang! According to Google, you are right. MY 1965 T-bird. My recollection was the same as @gman2304. But hey, that was a very long time ago.

Agreed. To me, the cool part was how it worked. No simple programming in the BCU like today. It took some clever ingenuity back then, to build a black box that did the job.

I personally do enjoy looking at the different sequential turn signals, to see how each model does it, and at the same time comply with federal regulations for a turn signal. Some of them are meh, while others are cool.

Because 99.999% of the time they are junk- installed by a minimum wage flunky using cheap splices. Just what I always wanted; a brand new car with a wiring harness hacked into by some guy who almost certainly can’t even spell “technician.”
I will never buy a car with that ridiculous garbage installed- new or used.

If its an awesome thing then they should change the law.

If I am expected to follow the law so should the car dealers.
Talking motorcycles here. A flashing light will alert the eye more so than a solid light. I don’t have the flashing brake light on my motorcycles but I do understand how it would alert the eye faster. It’s probably the reason emergency vehicles have flashing lights. I’ve also seen many motorcycles with modulating headlights for the same reason.
 
My wife said the same thing about the flashing 3rd brake lights.
My wife wanted one and has one. After you have been hit hard - airbags deployed - seatbelts locked on her/daughter - all power systems shut down automatically - then $9600 of rear end damage - big loss of trade value - it’s worth thinking about …

It’s too fast - nobody’s foot or system is that fast … then it’s solid.
No doubt they draw awareness - especially at night - and up high on SUV’s. Anyone notice the percentage of SUV’s lately …
