The high-mount brake light signals vehicles to the rear that the vehicle is stopped.
The high-mount brake light illuminates in conjunction with the operation of the brake switch.
The high-mount brake light is installed to the rear package trim.
The high-mount brake light has adopted a LED.
NOTE:
Fogging or condensation on the inside of the high-mount brake light may occur, however, it is a natural phenomenon occurring as a result of a temperature difference between the interior and exterior of the high-mount brake light and has no effect on the light performance. Fogging or condensation will dissipate when the temperature inside the high-mount brake light rises after the high-mount brake light is illuminated and a period of time has elapsed.
Without Mazda Radar Cruise Control (MRCC) system
When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
When the brake switch (No.1 signal) turns on, current flows from the battery to the high-mount brake light.
The high-mount brake light turns on.
With Mazda Radar Cruise Control (MRCC) system
When the brake pedal is depressed, the brake switch (No.1 signal) turns on.
When the brake switch (No.1 signal) turns on, a brake switch (No.1 signal) on signal is input to the brake light unit.
When the brake light unit receives a brake switch (No.1 signal) on signal, it supplies current to the high-mount brake light.
The high-mount brake light turn on.
NOTE:
Refer to "SMART CITY BRAKE SUPPORT (SCBS)" and "MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM]" for details.
Without Mazda Radar Cruise Control (MRCC) system
When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
When the transistor inside the rear body control module (RBCM) turns on, the brake light relay turns on.
When the brake light relay turns on, current flows from the battery to the high-mount brake light.
The high-mount brake light turns on.
With Mazda Radar Cruise Control (MRCC) system
When the operation conditions are met, the rear body control module (RBCM) turns on the transistor inside the rear body control module (RBCM).
When the transistor inside the rear body control module (RBCM) turns on, the transistor inside the brake light unit turns on.
When the transistor inside the brake light unit turns on, current flows to the high-mount brake light.
The high-mount brake light turn on.
