"Made in Taiwan" — A Mark of Quality

In a market flooded with low-cost, unbranded bulbs, manufacturing origin matters. This Neolux N580 bulb is Proudly "Made in Taiwan". This is a significant mark of quality, indicating superior manufacturing processes, higher-grade materials, and far stricter quality control than standard mass-market bulbs. The result is a more durable bulb with robust filaments that can withstand the vibrations and electrical fluctuations of daily driving.

What is a W21/5W (7443) Bulb?

This bulb is one of the most common and versatile bulbs in modern vehicles. The "W21/5W" name (a European ECE standard) tells you everything you need to know.

• W21W: This is the high-power, 21-Watt primary filament.

• 5W: This is the low-power, 5-Watt secondary filament.

• 2 Pole / Dual Filament: This bulb has two separate circuits and filaments inside its T20 wedge base. This allows it to perform two distinct functions in one lamp.

It is also known by its interchangeable SAE (American) part number: 7443. If your owner's manual or old bulb is marked with either W21/5W or 7443, this Neolux N580 is the exact correct replacement.

Key Applications for the N580 Bulb

The dual-filament design makes this bulb a multi-function workhorse, most commonly used for:

1. Brake Light & Taillight (Combined): This is the most popular use. The 5W filament provides the standard "taillight" that is always on with your headlights. When you press the brake pedal, the 21W filament ignites, creating a bright, unmissable "brake light."

2. Daytime Running Light (DRL) & Position Light: In other vehicles, the 21W filament serves as the bright, full-time "Daytime Running Light," while the 5W filament acts as the "position light" (parking light).

It is a standard fit for a huge range of Japanese, Korean, American, and European cars.
