580 (W21/5W) T20

W21/5W (580) LED Wedge Bulbs – Dual Filament LED for Brake & Tail Light Applications

Upgrade your vehicle’s rear lighting with our selection of W21/5W (580) LED bulbs, designed to replace traditional dual-filament halogen bulbs in brake, tail, rear position, and parking lights. These LEDs feature a T20 wedge base (W3x16q) and offer two brightness levels—low beam for tail/parking lights and high beam for braking.

With Canbus-compatible options available, these LED bulbs help prevent dashboard errors in most modern vehicles. They deliver brighter light, faster response times, and greater energy efficiency compared to standard halogen bulbs.

Ideal for cars, vans, and motorcycles, W21/5W LED bulbs offer a quick plug & play installation and a long service life—making them the smart upgrade for modern, reliable rear lighting.
