Key Features at a Glance

• High‑Intensity LED Technology: Provides bright, clear signals with minimal power consumption.
• Universal Compatibility: Fits a wide range of models including BMW Series 3 E36 Sedan, various compact and touring cars, and many other European vehicles.
• Robust Housing: Made from high‑grade polycarbonate with reinforced glass to withstand vibration, temperature extremes, and moisture.
• Precise Flash Timing: Built‑in microcontroller ensures consistent flash intervals for optimal visibility.
• Easy Installation: Standard mounting bracket and clear wiring diagram simplify the replacement process.

Design & Construction Details

The indicator’s housing is engineered from a dual‑layer polycarbonate shell. The outer layer offers impact resistance, while the inner layer protects the LED array from dust and water ingress. The glass lens is treated with an anti‑glare coating to enhance visibility in all lighting conditions.

Inside the enclosure sits a four‑LED cluster, each rated at 0.5 W. These LEDs are arranged to provide uniform illumination across the entire front or rear surface, ensuring that drivers and pedestrians can easily detect turn signals from any angle.
