What Are the Yellow Lights on a Car Called?: 1 Minute to Understand Car Light Indicators

The yellow lights on a car are commonly referred to as "turn signals" or "indicator lights." These exterior lights are designed to alert other drivers and pedestrians of your intent to turn or change lanes. Located at the front and rear corners of every vehicle, their distinctive amber color adheres to international safety standards, specifically regulated in most countries to ensure that the message they send is quickly recognizable and distinct from other lights, such as brake lights or headlights. In addition to turn signals, "side marker lights" on vehicles—often amber in color—serve to increase visibility of the car’s extremities at night or in poor weather conditions. The yellow color is chosen for its high visibility, making it ideal for communication on the road.

Tips 1:

As a designer, I find it interesting how even small details like the placement and brightness of indicator lights can affect both safety and aesthetics. In fact, when planning a garage or driveway lighting scheme, it’s crucial to consider visibility for vehicles as well as pedestrians. If you're rethinking your home layout to improve traffic flow and safety—even as it relates to parking and vehicle access—you might be inspired by a robust and intuitive room planner which gives you control over every element of your property design.
