AUXITO 3157 LED Bulbs 3156/3057 Fit — 6000K Cool White, 700% Brighter, Pack of 2

The AUXITO 3157 LED bulb is a high-output replacement for 3157/3156/3057-style automotive sockets, delivering a 6000K cool white beam that’s designed to be 700% brighter than stock halogen lamps.

These AUXITO bulbs combine a precision optical lens, 66 SMD chips and an aviation-grade aluminum body to increase visible output, control beam spread, and keep operating temperatures low. They’re non-polarity, plug-and-play replacements that fit a wide range of sockets used for reverse, backup, tail, brake, turn and parking lights. Built-in EMC suppression reduces interference with vehicle electronics while the lens softens hotspot glare for safer night driving without blinding other road users.

How much brighter are these bulbs compared with standard halogen lights?

Compared with most factory halogen bulbs, the AUXITO 3157 LEDs offer a dramatic rise in perceptible brightness thanks to the combination of numerous high-precision SMD chips and an optical projector lens. Brightness gains improve visibility for reversing and signaling tasks at night or in poor weather.

• Rated as up to 700% brighter than traditional halogen units.
• 6000K cool white color for crisp, high-contrast illumination.
• 66 SMD LEDs provide 360° full-angle light coverage.
• Optical lens boosts light transmission to about 95% for even spread.

Will they fit my vehicle and how easy is installation?

These bulbs are made to be a direct swap into common automotive sockets and are non-polarity, so most users can install them without tools or wiring modifications. Always verify your vehicle’s bulb type before buying to confirm fitment.

• Compatible with 3157, 3156, 3056, 3057, 4157, 4156, 3457, 4057, 4114 and similar sockets.
• Non-polarity design reduces installation errors—plug in either direction.
• Typical installation time: about 5 minutes per bulb for most cars.
• Suitable for reverse, backup, DRL, tail, brake, turn and parking lights.

How do they manage heat and electrical interference?

AUXITO uses an aviation-grade aluminum housing and a scratch-resistant optical lens to move heat away from the LED chips quickly, extending lifespan and sustaining output. An onboard EMC module minimizes electromagnetic noise that can disrupt radios, navigation or backup cameras.

• Aviation-grade aluminum body for accelerated heat dissipation.
• Optical lens reduces thermal stress on LED chips, improving longevity.
• Built-in EMC module helps prevent signal interference with electronics.
• Estimated lifespan around 30,000 hours under normal use.

Are there compatibility caveats or warning lights I should expect?

Most vehicles accept these bulbs without issue, but some cars with sensitive CANbus systems may show warnings, flashing or hyper-flash. Those behaviors don’t indicate a faulty bulb; they stem from the vehicle’s error-checking logic and are typically resolved with load resistors or CANbus adapters.

• Sensitive vehicles may require load resistors or CANbus decoders to stop flicker or dashboard errors.
• EMC module reduces but may not eliminate all interference on every vehicle model.
• Confirm socket type and check online fitment guides if unsure.
• If a bulb flickers, consider adding a resistor or consulting an automotive electrician.

Who is this for: drivers who want a high-visibility upgrade for reverse, backup, brake or signal lights—especially those who need brighter, whiter illumination for safer low-light driving. AUXITO 3157 LEDs are suited to DIY installers who prefer a fast, tool-free swap and to vehicle owners seeking long-lasting bulbs with improved beam control and reduced glare for other road users. If your car uses a CANbus-sensitive system, plan for a possible resistor or decoder installation.
