7443/7444 Red LED Brake Light Bulbs – Description and Overview

LED Tail Light Bulbs with Built-in Resistors – No Hyper Flash (Pair)

Best Performance in the Industry
Our ultra-bright 27W 1600LM 7443/7444 Parking, Brake, and/or Turn Signal LED Bulbs with built-in resistors are engineered to deliver maximum output with deep red illumination covering 360 degrees. Unlike other brands that place resistors on both filaments (which can cause the housing to melt or LEDs to fall apart), our CANBUS LEDs feature a built-in resistor only on the turn signal filament.

To further ensure longevity, we’ve included a cooling fan that activates only when the high filament is engaged, reducing heat during resistor use and protecting the LED from continuous heat exposure. This design eliminates hyper-flashing and prevents error codes, offering a direct replacement for factory incandescent bulbs—no extra resistors or components needed.

Best-in-Class Brightness
Each bulb features 12 high-performance 1860-style deep red LED chips and outputs 1600 lumens. This means your turn signals and brake lights will shine significantly brighter than stock incandescent bulbs.

Reliable Compatibility
These bulbs work with 99.8% of vehicles. While most vehicles will accept the LEDs without issue, some systems with highly sensitive computers may still require special handling.
