AUTOONE 7440/7443 T20 LED Bulbs 6000K White - Pack of 2, 3000LM High-Output Reverse/Backup Lights

These AUTOONE 7440/7443 T20 LED bulbs deliver bright 6000K white illumination at about 3000 lumens per bulb, designed as plug-and-play replacements for reverse, backup, tail, brake, turn signal, parking, and DRL applications.

If you want a high-output, long-lasting LED replacement that fits common 7440/7443/T20 sockets, the AUTOONE bulbs offer significantly higher brightness than stock halogens, wide-angle coverage, and robust thermal construction. They use 3030 and 4014 SMD chips with an internal IC driver and aviation-grade aluminum body to manage heat and support extended run times.

How much brighter are these bulbs compared with standard halogens?

These AUTOONE LEDs are engineered to be substantially brighter than typical halogen bulbs. Each bulb produces up to 3000 lumens with a 6000K color temperature, providing clearer white light and broader illumination for reversing and auxiliary lights.

• 3000 lumens per bulb, about 700% brighter than many halogen equivalents
• 6000K bright white light for improved scene visibility
• 360-degree light dispersion for fewer dark spots

Will these fit my car and how easy are they to install?

AUTOONE designed these LEDs for backwards compatibility with a wide range of sockets and part numbers. Installation is plug-and-play with non-polarity wiring on most vehicles, though a decoder or load resistor may be needed for some sensitive CAN-bus systems.

• Compatible with 7440, 7441, 7443, W21W and many equivalent sockets
• Non-polarity design—insert either way for most installations
• Free decoder available from the seller if your vehicle triggers errors

How durable are these LEDs and how do they manage heat?

The bulbs use full aviation-grade aluminum and a hollow design to dissipate heat more effectively than plastic housings, which helps maintain brightness and extend lifespan. A built-in intelligent IC driver protects against flicker and voltage fluctuations to keep the LEDs stable over time.

• Durable aluminum body and hollow channels for thermal control
• IP67-rated waterproofing for wet and road-splash conditions
• Rated life of up to 50,000 hours under normal use

What are the exact specifications I should check before buying?

Knowing voltage, size, and socket compatibility ensures a correct fit and function. These AUTOONE bulbs are low-power, high-output units intended for 9–18V DC automotive circuits and standard T20 sockets.

• Wattage: 7W per bulb; Current: ~0.58 A
• Chipset: 5× 3030 SMD + 18× 4014 SMD; Color temp: 6000K
• Dimensions: approx. 1.70 × 0.79 × 0.79 inch; IP67 waterproof

Who this is for: drivers who want a brighter, longer-lasting LED upgrade for reverse, backup, parking, DRL, tail or turn-signal lighting. These bulbs suit owners replacing dim halogens, anyone improving night-time reverse visibility, and DIY installers seeking a compact, plug-and-play LED option. If your vehicle’s computer system flags an error, AUTOONE provides support and can supply a decoder or recommend a load resistor to restore normal operation.
