Auxbeam 921 LED Backup Reverse Light Bulbs T15/912 8000LM 6500K CANBUS-Ready, IP67 Waterproof

Auxbeam 921 LED Backup Reverse Light Bulbs are a plug-and-play 912/921/T15 replacement that delivers 8000 lumens per pair of crisp 6500K white light for clearer, safer reversing.

These B21-series 921 LED bulbs upgrade standard halogen reverse lamps with dramatically higher brightness and a built-in CANBUS-ready driver to avoid error codes. Designed for simple installation and long life, the bulbs pair high-output LED chips with an aviation-grade aluminum heat sink and an intelligent constant-current IC to maintain reliable performance in everyday driving conditions.

How much brighter are these bulbs compared with stock reverse lights?

Auxbeam’s 921 LEDs increase visible light output significantly compared to factory halogens, improving rear illumination and making obstacles behind the vehicle easier to spot at night.

• 8000 lumens per pair — roughly 600% brighter than typical halogen backups
• 6500K xenon-white color for clearer contrast and color rendering
• Even beam pattern designed to light the backup zone without excessive scatter

Will they work with my vehicle’s computer system without error warnings?
