921/T15 GTR CARBIDE CANBUS 2.0 (RED)

The GTR Lighting Carbide Canbus 2.0 LED Light Bulb is an automotive lighting upgrade designed for increased brightness and safety. It features CNC anodized aluminum construction and a built-in CANBUS-integration circuit, eliminating the need for resistors in many applications.

This LED bulb utilizes a Constant Current Driver to regulate voltage, ensuring a steady current for extended bulb life, especially on vehicles with fluctuating voltage. The bulb design includes vents and heat sink fins for passive cooling and a temperature-controlled thermister circuit to prevent overheating. It fits signal, marker, brake, tail, and reverse lights.
