Front Brake Lights Could Drastically Diminish Road Accident Rates
The concept of a front brake light has been floating around the automotive industry for some time now. However, no vehicle manufacturer has yet embraced the idea and turned it into a reality on the

I still think rear signaling could be improved dramatically by using a wide third-brake light to show the intensity of braking.
For example -- I have seen some aftermarket turn signals which are bars the width of the vehicle, and show a "moving" signal starting in the center and then progressing towards the outer edge of the vehicle.
So now take that idea for brake. When you barely have your foot on the brake pedal, it would light a couple lights in the center of your brake signal. Press a little harder and now it's lighting up 1/4 of the lights from the center towards the outside edge of the vehicle. And when you're pressing the brake pedal to the floor, all of the lights are lit up from the center to the outside edges of the vehicle. The harder you press on the pedal, the more lights are illuminated.
Now you have an immediate indication of just how hard the person in front of you is braking. With the normal on/off brake signals, you don't know what's happening until moments later as you determine how fast you are approaching that car. They could be casually slowing, or they could be locking up their wheels for an accident in front of them.
Japan introduced brake lights that increase intensity based on how hard the driver was braking. 20+ years ago. They tested it in the US and drivers found it to be “confusing.”
BMW has implemented this in the US market for the past 20 years or so at least. Under heavy braking, additional brake lights turn on. I believe they call that Brake Force Display. I’m sure they’re not the only manufacturer to do this, too
BMW should focus on making the turn signals work first.
BMWs need a speeding indication more than a braking one /s
Haha, funny enough, some BMWs have a feature where the speedometer reads 5 MPH higher than actual vehicle speed. Probably to try cutting down on speeding
Plenty of cars flash their brake lights when ABS(/ESP?) engages, which is reasonable and should be a legal requirement IMO.
There's lots of room to give additional info in between that and "brake light is on because the driver doesn't understand that they can do mild adjustments by letting off the gas / stupid bitch-ass VW PHEV computer thinks using cruise control downhill with electric regen requires the motherfucking brake lights". It's like no-one realizes or cares that brake lights lose all purpose if they're on when the car isn't meaningfully decelerating. ARGH.
I suspect because there's no consistency in the brightness of vehicle lights. But that's one of the reasons why I think an incremental light bar would be better, there's no variation between vehicles. You could even make it more informative by flashing the whole bar when you first brake, so someone behind you can more easily see how much of the bar is being lit up.
If you want that, just light up the first and last LED always.
That's a good point, although flashing does help to grab attention, but it can also be annoying when the person is driving with their foot on the brake pedal.
If Japan introduced that they never caught on, unless it's specific to an area or model of car.
90% of the things that Japan introduced according to comment sections on the internet never happened (or never made it past the prototype stage) and the rest was actually introduced in Korea, not in Japan.
The Japanophilia is strong with a lot of people on the internet.
Yeah I mean I've been commuting 2 hrs a day in Japan for almost 10 years now-- you'd think I would've seen these brake lights by now
probably because thats a terrible way to do it. It would be noticeable if a car started braking and then started braking much harder, but if they slam on the brakes you don't see anything change, just a normal brake light.
I think that's a neat idea, but we could instead, collectively, just do better at following other cars at a safe distance. I know it's impractical to expect all drivers on the road everywhere to change their behavior, but it's also persistently frustrating as someone who has for years frequently been stuck in traffic to see 95% of drivers insist on following less than a car-length behind. Following too closely to enable decision-making or accommodate other drivers is the cause of like 98% of both traffic accidents and congestion, according to my completely anecdotal and made up research.
I suspect a lot of that has to do with the entitled way people are driving these days. If you leave a car length gap, some kid will wrecklessly attempt to cram their way in because your lane momentarily moved slightly faster.
There's this idea I've been considering for a long time.
Imagine putting a remote controlled firework smoke bomb under the tailpipe, hidden from sight. At best a really stinky one that smells like burned rubber or something.
When someone follows to closely, just fake an engine issue or something by activating the smoke bomb and fill their AC air intake with the smell of burned rubber for weeks. Just to teach them to not follow too closely again.
I think a secondary light that blinks quickly would be a good signal of emergency braking. Like some aftermarket motorcycle taillights that start with a blinking pattern before they stay on, but reverse the order.
So, standard brake light comes on at the standard time, at the first touch of the brake. For stronger braking, the second light comes on. For emergency braking, the standard brake light stays lit while the second light begins blinking frantically.
Edit for consistency
That could probably be implemented in most existing vehicles, and at least it would provide more information.
I think some cars also turn on the hazards automatically if you really hammer the breaks.
That would serve the same purpose without and extra light, I think they're into something
I see a lot of those on trucks here in the south. Good for when you are towing shit so people can see around all your junk in the trailer.
Does your state not require good lights on the trailers? I just built a new trailer last year, I was required to have full working brake and turn signals along with running lights, but I went the extra step and included more brake/turn lights on the front and rear of the fenders, along with reverse lights plus four marker lights along each side. Trailers are hard enough to see, I didn't want to make it harder for anyone by just sticking with the bare minimum.
I think only brake lights are required I've never seen turn signals on them. I suspect the ones I've seen with those aftermarket ones drive those trailers on other states with more strict requirements
Wow that's got to be almost worthless. As you say, it just takes some idiot with a load obscuring the vehicle lights and suddenly nobody behind them knows what's going on. What's next, are we going to make tail lights optional?
I have seen some cars flash their brake lights when ABS is activated, but this would be better
The EU has approved G-triggered brake lights that do just that, flash rapidly on hard braking. I’ve only seen it on higher end cars so far, but they absolutely exist. Unfortunately in the US people stick brake flashers that blink in patterns every time they touch the brake. Mostly useless as they’re installed to be “look at me, aren’t I cool with my blinky brake lights?” rather than any additional safety.
Seems much more complicated than having the brake lights rapidly flash during hard braking. But of course we couldn't do that in the US because our turn signals/hazard lights are red
Turn signals can be either red or amber in the US.
yeah, but they shouldn't be allowed to be red to begin with.
