AUXITO 3156/3157 CANBUS LED Reverse & Backup Bulbs Pack of 2 — White 4000LM, Built-in Resistor & Active Cooling

AUXITO 3156/3157 CANBUS LED bulbs are plug-and-play white reverse/backup/parking lamps delivering up to 4000 lumens per pair with built-in CANBUS compatibility and active cooling. These LED replacement bulbs are designed to upgrade factory halogen reverse and backup lights to a crisp, high-output white without complex wiring. The pair produces a dramatically brighter beam than stock bulbs, incorporates an intelligent driver to minimize dashboard errors on most vehicles, and uses a robust aluminum housing plus an active fan for long service life.

How much brighter are these than standard halogen bulbs?

The AUXITO LEDs are engineered for a substantially higher light output so reversing and parking lights are easier to see in low-light or adverse weather. Brighter illumination helps other drivers and pedestrians spot your vehicle sooner.

• Rated at approximately 4000 lumens per pair for a strong white beam
• High-brightness LED chips for clearer, more consistent light
• Designed to replace 3056, 3156, 3157, 3457, 3057, 4057, 4157 sockets

Will these work with my vehicle’s CANBUS system without errors?

The bulbs include an intelligent built-in driver intended to prevent error codes and bulb-out warnings on most modern vehicles. They are compatible with the majority of systems, though a small number of cars with unusual electronics may still require an inline load resistor.

• Integrated intelligent IC driver to reduce false error messages
• Compatible with roughly 98% of vehicles’ electrical systems
• Load resistors may be recommended for a few special vehicle models

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

AUXITO built these bulbs with a durable aviation-grade aluminum body and an active cooling fan to protect LEDs and electronics. The thermal design helps sustain performance and extends the bulb’s usable life.

• Sturdy aluminum housing for improved heat dissipation and durability
• High-speed cooling fan (approx. 12,000 RPM) to divert heat from components
• Estimated service life up to 50,000 hours under normal conditions

How easy is installation and what if I have problems?

These bulbs are intended for simple plug-and-play installation in compatible sockets, with no extra wiring in most cases. AUXITO provides customer support if you experience compatibility issues or need help identifying the correct bulb model.

• Plug-and-play fit for multiple socket types (3056/3156/3157/3457/3057/4057/4157)
• Pack of 2 bulbs for front/rear replacement or dual applications
• Customer support available for installation or compatibility questions

Who is this for Drivers who want a straightforward, long-lasting upgrade from halogen reverse, parking, daytime running, or turn signal bulbs to a brighter white LED. Ideal if you need higher visibility without rewiring, want a robust thermal solution for long life, and prefer a CANBUS-friendly option that fits multiple socket sizes. If your vehicle has an uncommon electrical system, be prepared to use a load resistor or contact support for guidance.

FAQ

Q: Do these bulbs fit my 3157 socket?

A: Yes — they’re made to replace 3056/3156/3157/3457/3057/4057/4157 sockets; confirm with your owner manual.

Q: Will I get a dashboard bulb error after installation?

A: Most vehicles won’t show errors due to the built-in CANBUS driver, but a few models may still need a load resistor.
