AUXITO 3157 LED Bulb 6000K White — Pack of 2, 54‑SMD 360° Bright Reverse/Tail Light

The AUXITO 3157 LED bulb is a high-output, 6000K white replacement for 3157/3156/4157-style exterior vehicle lamps, delivering brighter, energy-efficient reverse, backup, tail, and parking light illumination.

These AUXITO 3157 bulbs use an array of 54 4014-SMD LEDs arranged to mimic halogen bulb shape and provide 360° coverage, producing crisp white light for improved visibility around the vehicle. At just 5.5W per bulb, they draw far less power than conventional bulbs while offering much greater brightness. Built-in smart IC drivers regulate current for stable performance and zero warm-up time, and the electroplated housing reduces heat and corrosion for longer-lasting operation.

How bright are these bulbs compared to stock halogen lamps?

Each AUXITO 3157 bulb produces a concentrated 6000K white output using 54 SMD chips to increase perceived brightness and coverage around the socket. You’ll get clearer illumination for reversing and parking without the slow warm-up of older designs.

• 54 x 4014-SMD LEDs arranged for 360° light distribution
• 6000K crisp white color for high contrast visibility
• Only 5.5W per bulb — far lower power draw than halogen equivalents
• Instant-on performance with stable current via built-in smart IC driver

Will these fit my vehicle and the 3157/4157 family of sockets?

The bulbs are sized to closely match OEM 3157-style fittings and are non-polarity, so most US-standard CK and wedge sockets accept them. They’re compatible with many related part numbers (3056, 3057, 3156, 3157, 4057, 4157, 4114, etc.), but always verify your vehicle’s bulb type before purchase.

• Form factor designed to match halogen 3157 family sockets
• Non-polarity for straightforward installation in most vehicles
• Compatible uses: reverse/backup, DRL, turn signal, parking, tail, marker lights
• Exception notice: Not compatible with 2018–2022 Ford F-150 reverse light sockets

How durable and heat-resistant are these AUXITO LED bulbs?

The housing uses an electroplating process to resist oxidation and help dissipate heat, extending service life compared with typical bare-plastic replacements. The smart IC driver keeps current steady, preventing flicker and reducing electrical noise, while the compact construction eases fitment in tight lamp compartments.

• Electroplated housing for improved corrosion and heat resistance
• Smart IC driver for constant current and reduced interference
• Compact shape designed for OEM-like fit and easier installation
• Robust SMD array that maintains brightness with lower energy use

Are there installation tips or compatibility checks I should know about?

Installation is typically plug-and-play thanks to the non-polar design, but verify the bulb family in your owner’s manual or remove the old bulb to confirm fit. Some vehicle models use CAN-Bus systems or have unique sockets—if uncertain, consult the manual or ask for help with your vehicle details.

• Confirm your vehicle’s bulb type in the owner’s manual before buying
• Remove old bulb to compare size and base if unsure
• Some vehicles may require CAN-Bus adapters or resistors for error messages
• AUXITO advises checking fit for specific models (e.g., 2018–2022 F-150 reverse lights are incompatible)

Who is this for: Drivers seeking an energy-efficient, bright white upgrade for exterior auxiliary lights — especially reverse, backup, parking, and DRL applications — who want easy plug-and-play installation and improved nighttime visibility. These AUXITO 3157 bulbs suit DIY car owners, fleet operators, and anyone replacing worn halogen bulbs, provided they confirm socket compatibility for their specific vehicle model.
