What this product is and who it fits

AUXITO 7443/7440 LED strobe brake bulbs replace standard rear lamps on cars, trucks and SUVs. Each unit contains 54 pieces of 4014-SMD chips arranged in a halogen-style outline for 360° red output. The pack supplies two bulbs weighing 0.032 kg total and draws 5.5 W per bulb. They suit 7440, 7441, 7443, 7444, W21W and listed cross-reference numbers.

Check your vehicle before ordering

Confirm the original bulb is a 7443 or 7440 type by reading the owner manual or the marking on the old lamp. Some sensitive CAN-bus systems will hyper-flash or throw a dashboard warning; if that occurs, 50 W 6 Ω load resistors or a compatible flasher relay are needed. The bulbs fit US standard and CK sockets without polarity concerns, but aftermarket housings may not match the OEM fitment guide.

Behaviour under sustained braking

When the pedal is pressed, the bulbs flash three rapid on-off cycles then hold a steady red glow, meeting legal blink counts. The built-in IC driver maintains constant current so brightness does not fade during long stops and no radio interference appears. Instant-on response with zero warm-up repeats reliably every activation, and low power draw reduces load on the charging system during extended use.

Questions about this item

What comes in the pack and is anything else needed for installation?

The pack contains two red 7443/7440 LED strobe brake light bulbs. Some sensitive vehicles may need load resistors or a flasher relay to prevent hyper-flash or dashboard errors.

Which bulb version should I choose for a 7443 or 7440 socket?

These bulbs fit 7440, 7441, 7443, 7443LL, W21/5W, 7443/26201, 78660, 78661, 17919, 7515, HIB7443WM, W21W, 7440/26200, 17632, 7504 and 7440LL sockets.

What does the 5.5 W rating mean when the bulbs are running in my car?

Each bulb draws 5.5 W — roughly one-quarter of a standard halogen — while the 54 SMD LEDs give several times more brightness with instant-on response.
