Description

The Osram Diadem Chrome PY21W (7507DC-02B) is an auxiliary signal lamp designed to provide a sleek, modern aesthetic to your vehicle's exterior lighting. Its standout feature is the innovative Diadem Chrome design, which utilizes advanced interference and absorber coating to create a mirror-like chrome finish. This chrome surface is only visible when the lamp is off, giving it a discreet appearance. When activated, the lamp emits a distinct amber light, ensuring proper signaling while maintaining a clean, homogenous look within the housing.
