The **direction indicator light** is an essential tool in vehicles to communicate your intentions on the road to other drivers. This light, yellow in color and flashing intermittently, should always be used when you are going to **change direction, change lanes, or make a U-turn**. This means that if you plan to turn around and change the direction of your travel, it is correct to use this light to alert others.

The **R.S.M. safety rule** also reinforces this practice, indicating that you should turn on the direction light on the side you are going to move towards, whether for a lane change, a change of direction, or a U-turn. This ensures that other drivers are aware of your movements and can act accordingly, improving road safety.

Therefore, it is correct to state that you can use the direction indicator light to signal a change in the direction of travel.
