AUXITO 912/921 Red LED Bulb for 3rd Brake/CHMSL — Pack of 2, CANbus Error‑Free, Bright 2835 SMD

AUXITO 912/921 red LED bulbs are plug-and-play replacement bulbs designed for your vehicle's third brake/center high mount stop light, delivering brighter red illumination without CANBUS errors.

These compact T15-compatible LEDs (fits 912, 921, 906, 904, 922, W16W sockets) upgrade the center high mount stop light with long-lasting 2835-SMD diodes and an intelligent IC driver. Each bulb draws low current from 12–16V systems, fits in tight housings, and aims to improve visibility and the appearance of your rear lighting while avoiding dashboard error codes on many modern vehicles.

How much brighter are these AUXITO bulbs compared to stock bulbs?

Each AUXITO 921 replacement contains 15 high-power 2835 SMD LEDs engineered to output a strong red light that appears significantly brighter than many original incandescent third brake bulbs. Brighter illumination helps the stop light stand out more clearly in daylight and at night without increasing size or heat drastically.

• 15 pieces of 2835-SMD LEDs per bulb for high lumen output
• Rated 6W per bulb with efficient light conversion
• Designed to produce a noticeably stronger red signal vs. stock

Will these work in my car without triggering CANBUS or dashboard errors?

These bulbs include a built-in intelligent IC driver intended to stabilize current and mimic OEM load characteristics, reducing the chance of CANBUS error messages on many vehicles. While engineered to be error-free in most systems, compatibility varies by make, model and trim, so checking the vehicle's bulb specifications is recommended.

• Integrated IC driver for steady operation and error suppression
• Energy-efficient design to limit heat and electrical noise
• Not guaranteed for all vehicles—verify compatibility when concerned

What sockets and applications suit these LED bulbs?

These AUXITO bulbs are sized to match common T15-type sockets including 912, 921, 906, 904, 902, 922 and W16W. They are intended for use as a third brake/center high mount stop light, backup reverse accent, tail light or other compatible positions where that socket type is used.

• Direct-fit for T15-style sockets listed above, plug-and-play installation
• Bulb dimensions: approximately 1.57 in long by 0.59 in wide by 0.35 in high
• Applications: third brake light, high mount stop light, tail light accents

How durable and energy-efficient are these replacement LEDs?

The AUXITO 921 bulbs are engineered for long life and low power consumption, drawing modest current at typical automotive voltages. Their compact profile and efficient LEDs help keep operating temperatures lower than many incandescent bulbs, which contributes to longevity.

• Operating range: 12–16V, 500mA current specification noted
• Net weight ~6 grams per bulb to preserve fit in tight housings
• Low heat output and energy-saving operation compared with incandescent bulbs

Who is this for? Drivers who want an easy, compact upgrade to their center high mount stop light or similar T15 sockets—those seeking brighter red illumination, lower power draw and reduced risk of CANBUS errors on many vehicles. If you value plug-and-play installation and clearer rear signaling appearance, these AUXITO LED bulbs are a practical aftermarket option; however, confirm your vehicle’s exact bulb size or consult the owner’s manual to ensure an accurate fit before ordering.
