Tesla to implement new hazards light pattern that drastically improves safety

A small, four-year-old company in Houston, Texas, has been using a Tesla Model 3 to demonstrate its revolutionary hazard warning system. Now, their system will be in millions of Teslas.
Emergency Safety Solutions, Inc. (ESS), is the creator of HELP, which stands for Hazard Enhanced Location Protocol. The company claims its system significantly improves driver safety. Tesla, which usually develops its systems, and rarely uses external programs, will be the first automaker to implement HELP in its vehicles.
ESS says that every seven minutes, there is a crash involving a disabled vehicle on American roadways. These crashes kill or injure 15,000 people annually. The company also states the main factor in those crashes is an ineffective hazard light system that is not getting the attention of drivers. The hazard light system was created more than 70 years ago and hasn't been improved since.
According to ESS, HELP will: "provide advanced lighting alerts and digital location-based alerts to greatly improve advance warning communications to drivers." Virginia Tech Transportation Institute studied several lighting combinations and found that 4hz to 6Hz flash frequencies greatly improved drivers' attention. The current system is 1.5Hz.
Researchers then took the 5Hz system to the street and found that drivers responded 12 seconds earlier. They also discovered that drivers moved over 360 meters or nearly four football fields away from the disabled car. In addition, drivers moving to the left of a disabled car jumped from 30 percent with the current system to 87 percent with HELP.
The flashing lights will undoubtedly improve safety, but the system also sends a digital signal to alert drivers using in-car or phone navigation that there is a hazard ahead. The early warning will allow drivers to be warned much sooner than just the visual blinking lights system. Additionally, the HELP system can be manually activated or it will automatically turn on if a collision is detected or an airbag is deployed.
Tom Metzger, CEO of ESS, said, "Tesla is a leader in bringing first-time innovation to passenger vehicles and is leading the way by implementing HELP technology on potentially millions of Tesla vehicles worldwide. It's a monumental step in the effort to overcome the troubling safety issue of crashes into disabled and vulnerable vehicles, which tragically injure or kill tens of thousands around the world each year."
New Hazard Light Pattern on a Model 3
Tesla will implement these changes to these existing vehicles through a software update. It's a rare step for Tesla, which usually creates its own systems and improves traditional programs (Tesla recently improved the seatbelt).
This time Tesla found a company that has done everything necessary to improve this aspect of vehicle safety, so why recreate the wheel?

Tesla regularly holds quarterly all-hands meetings for employees, but last night marks the first time Tesla has live-streamed the event for the public.
The meeting primarily focused on Tesla’s employees, recent achievements, and the future of Tesla. While it didn’t reveal much new information, it was interesting to see Elon Musk candidly engaging with his teams, who seem to genuinely enjoy working with him. Still, there were a few noteworthy takeaways.
As with Tesla’s Earnings Calls and other live events, we’ve put together a concise, easy-to-digest recap of everything discussed.
General Points
Work-related Injuries declined over time
Planning to expand to new markets
Cell Manufacturing
Continuing to invest in battery supply
Cheapest, lowest cost per kWh cell
The supercharger network continues to grow
Vehicle range and charging speed should match the needs of humans and their required time for breaks
The Super Manifold is Tesla’s solution to reducing the complexity of a heat pump system for an EV. Tesla showed off its engineering chops back with the original Model Y in 2019, where it introduced a new 8-way valve (the Octovalve) and a new heat pump alongside the uniquely designed Super Manifold to improve efficiency.
Now, Tesla is launching an improved version with the refreshed Model Y - the Super Manifold V2. We got to hear about it thanks to Sandy Munro’s interview with Tesla’s Lars Moravy (Vice President of Vehicle Engineering) and Franz Von Holzhausen (Chief of Vehicle Design). You can watch the video further below.
What Is The Super Manifold?
The Super Manifold (get it, Superman?), is an all-in-one package that brings in all the components of a heat pump system into one component. The Super Manifold packs all the refrigerant and coolant components around a 2-layer PCB (printed circuit board).
This Super Manifold would normally have 15 or 20 separate components, but Tesla managed to integrate them all into one nice package. That presented Tesla with a new challenge: how to integrate a heat pump—capable of both heating and cooling—into a single, efficient platform?
Several years ago, Tesla designed the Octovalve. It combines inlets and outlets and can variably change between heating or cooling on the fly - without needing to be plumbed in different directions. This is especially important for EVs, which may need to heat the battery with the waste heat generated from the motors or the heat pump while also cooling the cabin - or vice versa.
Original Super Manifold V1.1
Tesla launched the Super Manifold V1.1 back in 2022, and it provided some minor improvements to the waste heat processing of the heat exchange system. It also tightened up the Octovalve, preventing the leakage of oils into the HVAC loop that could cause it to freeze at extremely low temperatures.
Tesla has been using the V1.1 for several years now, and it has really solved the vast majority of issues with the heat pump system that many older Model Ys experienced.
Super Manifold V2 Coming Soon
Now, Tesla is introducing the Super Manifold V2 in the new Model Y. It will improve the overall cooling capacity provided by the original Super Manifold, but unfortunately, not every single new Model Y will come with it equipped. Tesla will be introducing it slowly across the lineup and at different rates at different factories, depending on part availability.
Eventually, the Super Manifold V2 will also make its way to other vehicles, potentially including the upcoming refresh for the Model S and Model X, but initially, it’ll be exclusive to the new Model Y. Tesla expects to have the new manifold in every new Model Y later this year.
