Auxbeam 7440 LED Backup Reverse Light Bulbs B2 Series 6000LM 44W — CAN-Bus Compatible, Plug-and-Play

If you want a brighter and more reliable reverse light without complex wiring, the Auxbeam B2 Series 7440 is designed as a direct replacement for common 7440-style sockets. These bulbs prioritize intense white illumination, durable construction, and compatibility with modern vehicle electronics so you can upgrade your backup lighting quickly and with minimal fuss.

How much brighter are these bulbs compared with stock halogen reversing lights?

The B2 Series replaces yellowish halogens with a crisp, high-output LED array that produces substantially more visible light. Expect a dramatic increase in lumen output and a whiter color temperature for improved contrast when backing up at night.

• Rated output: up to 6000 lumens per bulb set.
• Power draw: 44W maximized brightness per bulb set.
• Perceived brightness: roughly multiple times brighter than typical halogen reverse lamps.

Will these LEDs work with my vehicle’s electrical system without flicker or warnings?

Auxbeam built the B2 Series with an intelligent driver to address common LED issues such as flickering and dashboard bulb warnings. The driver is engineered for broad compatibility so most CAN-Bus systems accept it without extra resistors or decoders.

• Integrated smart driver reduces flicker risk.
• Designed for CAN-Bus compatibility; minimal false-warning potential.
• No additional load resistors or decoders typically required.

How does the B2 Series handle heat and vibration for long-term use?

Heat management and mechanical durability are central to the design: an aviation-grade aluminum housing rapidly dissipates thermal energy while providing strong resistance to shocks and vibration. That combination helps maintain brightness over a long service life.

• Thermally conductive aluminum casing for efficient heat removal.
• Vibration-resistant construction suitable for trucks and off-road vehicles.
• Expected extended operational life compared with typical halogen bulbs.

Is installation straightforward and which sockets are supported?

These bulbs follow a 1:1 form-factor for easy, play-and-plug installation with non-polarity wiring, so most users can swap them in without tools beyond access to the socket. The B2 Series fits many common 7440-style sockets and is intended for reverse and backup light upgrades.

• Non-polarity design simplifies installation.
• Compatible with 7440, 7440A, 7440NA, 7440AL, 7440LL, 7441, 992, W21W, WY21W, and similar sockets.
• Recommended: verify original bulb number or owner’s manual before purchase.

Who is this for: Drivers who need a brighter, longer-lasting reverse light—especially owners of trucks, SUVs, and off-road vehicles—will benefit from the Auxbeam B2 Series 7440 bulbs. If you want a straightforward upgrade that improves rearward visibility and integrates smoothly with modern vehicle electronics, these bulbs offer a high-power, durable option without the need for complex additional wiring.
