SYLVANIA 7443R Red LED Brake Tail Stop Light Bulbs T20 Wedge Dual Intensity
Description
SYLVANIA 7443R (7443RSL.BP2) Red LED miniature replacement bulbs deliver instant-on signaling illumination, energy-efficient dual-intensity performance, and solid-state durability for compatible automotive rear lighting systems. Designed as a direct plug-and-play upgrade for standard dual-filament T20 wedge sockets (7443, W21/5W), each bulb operates at 12.8V with dual-mode wattage consumption: 1.3W on high intensity (brake/stop) and 0.4W on low intensity (tail/running). Featuring lead-free RoHS-compliant construction and integrated compatibility with standard bulb outage detection circuits, these bulbs resist road vibration while providing reliable signaling. Designated for off-road exterior use and custom styling behind red lenses.
Package Includes: 1 × Factory Sealed Blister Pack (2 × SYLVANIA 7443R Red LED Bulbs).
