Amber LED Turn Signal Performance

The TecNiq T40 turn signal light provides bright amber LED output in a compact 4″ round housing. LED technology offers fast response time, low power draw, and longer service life compared to traditional incandescent turn signal lights.

Amber Lens or Clear Lens Options

Choose a traditional amber lens for a classic signal light appearance or a clear lens for a cleaner, modern look. Both configurations illuminate amber and are designed for turn signal applications.

Tri-Pole Connector or Pigtail Wiring

Select the wiring configuration that best fits your installation. Tri-pole connector versions provide quick-connect installation and easier future serviceability, while pigtail wiring versions feature integrated wire leads for direct hardwired installation.

Flange Mount Installation

The T40 flange-mount design provides a secure surface-style installation without requiring a separate rubber grommet. This makes it a strong choice for repairs, upgrades, and custom applications where a flange-mounted 4″ round turn signal light is preferred.

Built for Harsh Environments

Featuring TecSeal urethane-potted electronics, impact-resistant polycarbonate construction, and an IP68 waterproof rating, the T40 is engineered to perform in rain, mud, dust, road salt, vibration, and demanding outdoor conditions.

Made in the USA

TecNiq manufactures the T40 in the United States using premium materials and rigorous quality standards. Each light is backed by TecNiq’s Limited Lifetime Warranty for long-term confidence and reliability.
