Turn Signal Light
The parking light is also a standard vehicle item. Along with the turn signal lights, the parking light is a crucial component in ensuring the safety of the vehicle. To approaching traffic, the Parking Light makes the vehicle more visible, especially from the side view. This improves safety in entering an intersection or making turns as it allows other drivers to see your vehicles from greater distances.
Aside from warning against other vehicles, the parking light is also used in bad weather conditions (like heavy fog or snow) which minimizes normal visibility. The poor light of dusk and dawn hours can be worse for the driver's vision than driving at night. The parking light solves that driving problem.
