DUAL FUNCTION SAFETY: NEOLUX by OSRAM P21/4W 12V Lamp (N566) – OE-Spec Dual Filament.
END TAIL LIGHT FAILURES. RESTORE DUAL CIRCUIT SAFETY. GET THE PRECISION METAL BASE BULB FOR YOUR EUROPEAN/ASIAN VEHICLE.
The P21/4W (also known as the 566 bulb) is a specific dual-filament halogen bulb used for combined safety lighting functions, primarily the Tail Light (4W, dim) and Brake Light (21W, bright) in many European and Asian vehicles (e.g., specific models of BMW, Mercedes-Benz, Peugeot, Renault, and VW/Skoda).1 This bulb is critical because its BAZ15d base has displaced pins (angled at different heights) to ensure the bulb can only be inserted one way, preventing the 4W filament from being used as the brake light and vice versa.
The NEOLUX by OSRAM P21/4W Lamp (Part No: N566) is the trusted, ECE-certified replacement.2 As a brand backed by OSRAM and manufactured in Slovakia (EU), this bulb guarantees the necessary dual-circuit function, precise filament geometry, and superior quality for critical safety signaling.
THE CORE SPECS: Dual Filament Metal Base (BAZ15d)
This bulb is engineered for precise dimensional fit and reliable dual-circuit electrical function.
| Specification | Detail | Direct Benefit to the Egyptian Driver |
| Neolux Part No. | N566 (OSRAM Ref: 7225) | Dual Function. Handles both the 4W (Tail/Parking) and 21W (Brake/Stop) functions. |
| Bulb Type | P21/4W | Single Point Source. Halogen bulb with two separate filaments inside one glass envelope. |
| Voltage/Wattage | 12V / 21W & 4W | OE Power Match. Ensures the correct brightness for both the running light and the critical brake signal. |
| Base Type | BAZ15d (Metal Bayonet, Displaced Pins) | Safety Feature. The offset pins prevent accidental insertion into a single-filament socket (BA15s) or reverse polarity, ensuring the brake light is always the brighter filament. |
| Luminous Flux | ~440 lm (Bright) / ~15 lm (Dim) | Clear Visibility. Delivers the correct, legally mandated light output for brake signaling. |
| Origin | Made in Slovakia (EU / NEOLUX by OSRAM) | Trusted Quality. Backed by a globally recognized lighting leader, ensuring filament accuracy and longevity. |
WHY NEOLUX N566 IS YOUR CRITICAL PURCHASE NOW
You are choosing reliability and guaranteed visibility for safety-critical communication on the road.
Guarantees Brake Light Function: A functioning brake light is paramount for rear-end collision avoidance. This bulb ensures your brake signal is bright, rapid, and unmistakable.
Prevents Mis-Wiring Hazards: The BAZ15d displaced pins are essential. They ensure the powerful 21W filament is correctly wired to the brake circuit, and the dimmer 4W filament to the running light circuit, preventing dangerous lighting errors.
Filament Durability: Built with robust materials to resist the shocks and vibrations of driving, offering reliable performance and minimizing premature failure of the filaments.
OE-Spec Quality: NEOLUX provides the certified quality needed for vehicle safety at a competitive price.
SECURE YOUR REAR LIGHTING SAFETY.
Don't compromise safety with a dim or failed brake light. Always replace bulbs in pairs for symmetrical illumination.
Crucial Check: Verify your vehicle uses the dual-filament P21/4W bulb with the BAZ15d (displaced pin) metal base.
