Which of these lights is not a position light with fixed intensity?
Lighting
Explanation
The **direction indicators** are lights used to signal that a vehicle is going to turn or change lanes. These lights are yellow and operate in a **flashing** manner, meaning they turn on and off repeatedly. This differentiates them from other vehicle lights that have a **fixed intensity**.
On the other hand, the **brake lights** and the **rear fog light** are lights with fixed intensity. The brake lights, which are bright red, turn on when the driver presses the brake to indicate that the vehicle is slowing down or stopping. The rear fog light also has a fixed intensity and is used to improve the visibility of the vehicle in foggy conditions.
Therefore, the **direction indicators** are the only lights that do not have a fixed intensity, as their flashing function is essential to communicate the driver's intentions to other road users.
