Sidemarkers & Indicators

Sidemarkers and indicators, also known as turn signals are essential components of a vehicle’s lighting system, designed to increase visibility, indicate directional intent, and improve overall road safety. These lights—commonly installed along the sides, corners, or front and rear fenders of a vehicle—help other drivers gauge a vehicle’s position and movement, especially at night or during low-visibility conditions. This category includes various lighting components such as turn signal bulbs, side marker lights, and corner lights, each serving a distinct purpose in signaling and vehicle awareness.

Modern indicator systems may use halogen, incandescent, or LED technology. LED turn signals are increasingly common due to their faster illumination time and longer operational lifespan, which contributes to improved driver communication and safety.

Lighting regulations vary by region, so it’s important to ensure that side marker lights and indicators meet local vehicle safety standards (e.g., SAE/DOT in North America or ECE in Europe). Most sidemarker and indicator assemblies are designed for direct OEM replacement or aftermarket customization, and installation typically involves plug-and-play connections or minor wiring modifications.
