Auxbeam B2 Series 7440 LED Backup/Reverse Bulbs 44W 6000LM — White High-Output, Anti-Flicker

The Auxbeam B2 7440 LED is an upgraded reverse lamp engineered to replace yellow halogens with intense white light. Built with multiple high-brightness chips and an aviation-grade aluminum body, this bulb prioritizes light output, thermal management, and vehicle compatibility so you get reliable illumination while backing up in low light or poor weather.

How much brighter are these bulbs compared with stock halogens?

These LEDs produce up to 6000 lumens per bulb set, which is roughly five times the brightness of many original halogen reverse bulbs. Expect a more visible area behind the vehicle and crisper contrast for obstacles and roadside edges.

• Up to 6000 lumens output for each bulb set
• Approximately 500% brighter than standard halogen reverse lights
• High-brightness chips arranged for broad and consistent beam spread

Will these fit my car and trigger warnings?

The B2 7440 bulbs use a 1:1 mechanical fit for common reverse lamp sockets and include an intelligent driver to prevent flicker and dashboard error codes. They’re designed to work without extra resistors or decoders on most CAN-Bus systems.

• Compatible with 7440 family sockets: 7440, 7440A, 7440NA, 7440AL, 7440LL and related types
• Works with 7441, 992, W21W, WY21W socket standards
• Built-in anti-flicker driver reduces the need for additional wiring or adapters

How durable and long-lasting are these LEDs?

The housing uses aviation-grade aluminum to move heat away from the chips quickly, improving longevity and maintaining stable output on extended drives. The robust construction also improves resistance to vibration for trucks and off-road use.

• Rapid heat dissipation design for prolonged LED life
• Rated for long service life and strong vibration/shock resistance
• Suitable for trucks, SUVs, and vehicles used on rough terrain

How easy is installation and which applications are ideal?

Installation is straightforward: the bulbs are non-polarity, plug-and-play replacements matching halogen form factors. They are ideal as direct reverse/backup light upgrades and require minimal mechanical effort to install.

• 1:1 design for direct replacement—no special tools needed
• Non-polarized for simple swap-in installation
• Intended for reverse and backup light applications to increase visibility

Who is this for: The Auxbeam B2 7440 LED bulbs suit drivers who want a dramatic visibility upgrade from standard halogen reverse lights—especially owners of trucks, SUVs, and off-road vehicles who need bright, durable illumination when backing up in low light or poor weather. Before ordering, check your vehicle owner’s manual or the existing bulb number to confirm compatibility. If you encounter any issues, Auxbeam support is available to assist with fit and troubleshooting.
