If we can not get sequential tail lights it would be nice if someone made something that makes the brake lights brighter for an instant like I see on the fire trucks and other emergency vehicles. When you brake the brake lights start extra bright for a split second before going to the regular brightness.

Lexus should be able to equip the US-spec RXs with sequential turn signals. As others have said, US-spec cars like the Mustang and new Audi Q3, have sequential turn signals. I wonder if they are exempt since the brake lights are used as the turn signals too.

That probably would be illegal...but I wish that we had the feature like in European cars where the brake lights flash when emergency braking to tell drivers behind to prepare.

Being on the design team for rear signal lighting and currently the manufacturing engineer for the 760A project I would like to address some of your concerns.
Will the US get the sequential tail lights? No.
Can you turn your current lamps into sequential tail lights? No
But I bet you would like to know how to get them? I can answer that..
Background: The 760A is the model that is built at TMMC (Toyota Canada) for the north american market. 740A is the model built in Japan for the ECE, CCC, and Japanese market.
The 760A RCL (Rear Combination Lamp) and BUL (Back Up Lamp) as well as the head light are built in the US, The 740A's are built in Japan.
Due to new cars having a CAN system(Controller Area Network) almost every component has a "computer" or more specifically, some sort of electronic circuitry that can communicate with the body computer. In the RCL and BUL these "computers" will report any outage issues as well as a current on vs off function for the lamp.With that being said, what determines how the lamp lights up is the computer that is INSIDE the lamp. So unless you swap out said computer and design you own computer (which is impossible without destroying your lamp) you will not get sequential turn signals.
However! For the North American market there are 2 grades of lamps, High and Base Grade, High Grade has the LED Turn function. Base has bulb turn. all four lamps have the same vehicle mating connector, as well at the 740A has the same mating connector.
So, If you have the base grade lamps, you could, in theory, just source some Japanese built lamps and attach them to your RX and BOOM Sequential tail lights!
If you have bought your North American RX with the High Grade lamps, the computer is the same in the RCL between the 760A and the 740A. which means that all you would need is the BUL from the Japanese market. This is because the High Grade RCL and BUL have a common communication between the lamps. This communication tells the RCL to light up after the BUL has completed its sequence.
I hope this helps, from one car guy to another.

Thanks dude for the info, when you say BUL, can you tell me in "English" which part is this?, when you say that you don't recommend to do this its because it's illegal or because could damage the electric system of the car in case it's wrong? Canadians RXs have sequential light?, thanks again

What I wonder is, can I "plug and play" the lights from japan and then the computer in the new light can communicate with the ECU of the car automatically?
