The 13?diode LED 1156 bulb is a universal aftermarket replacement designed to fit standard 1156 single?filament sockets used in turn signals, brake lights, tail lights, and marker lights. Featuring 13 bright LEDs mounted around a compact housing with a clear lens, this bulb typically uses less power and produces less heat than traditional incandescent bulbs while offering a longer expected service life. Sold individually as a non?OEM component, it includes a warranty against defects in workmanship and materials from the date of purchase. Because it's intended for universal use, confirming compatibility with your specific lamp housing and vehicle electrical system before installation is recommended.
