All our T20 W21/5W 7443 LED Bulbs

The T20 W21/5W base (also called 7443) is a dual-filament bulb used for brake/parking lights, daytime running lights (DRL), and reverse lights. “W21/5W” means it combines a 21 W filament (brake) and a 5 W filament (parking light). Our T20 W21/5W LEDs reproduce this dual function.

White is intended for daytime running lights (DRL) and reverse lights, while red is suitable for brake lights and rear parking lights. The White Angel is ideal for daytime running lights, and the Red SMART for highly visible brake lights.

Yes, several models include an anti-error module. The Luxoa Super CANbus red is specifically designed for the most demanding vehicles and prevents any error message or hyper-flashing on the dashboard.

Installation is very simple: just remove the original T20 halogen bulb by making a quarter turn, then insert the LED bulb in its place. No tools or additional wiring are required. Check the polarity: if the bulb does not light up, turn it 180°.

Each range has its strengths: the Angel offers excellent value for money, the SMART enhanced CANbus compatibility, and the Endura focuses on longevity. The VORTEK MAX offers, for its part, maximum luminous power.

The T20 W21/5W LEDs are sold individually and remain very affordable. The entry-level Angel is the most affordable, while premium models, like the VORTEK MAX, offer superior performance at a slightly higher price. Check each product page to find out the current price.
