Question about Car Audio & Video
Since your car is relatively new, I would say the brightness signal is controlled through your on-board computer. If it's not, then the brightness knob is essentially a dimmer switch (such as those found in your house). It controls the amount of voltage being sent to the lights/LEDs and this voltage is proportional to brightness. The more voltage, the brighter they burn and vice versa. If you want even more detail, the know is probably made of a potentiometer (variable resistor). These are extremely cheap resistors that can be replaced (assuming you can find the correct replacement).
Hope this helps!
