1157 Led Turn Signal Bulb

The twin-contact bayonet base allows this 1157 LED turn signal bulb to operate on two separate circuits. In high mode, the 520LM output is intended for clear flash visibility during lane changes and turns. In low mode, the bulb steps down to 144LM for use as a daytime or nighttime running light. The 27 SMD chips are arranged to project light in multiple directions, which helps fill the reflector housing evenly and reduces dark spots commonly seen with single-direction LED replacements.

Measuring 43mm in total length and 19mm in diameter at the upper section, this 1157 LED turn signal bulb fits most factory housings without clearance issues. The aluminum body acts as a passive heat sink, drawing warmth away from the LEDs during extended operation. Since there are no cooling fans or external drivers, the bulb runs silently and has fewer mechanical components that could fail over time.

This 1157 LED turn signal bulb is produced at a facility with ISO9001 and IATF16949 certification. Each unit is tested for voltage and basic function before packaging. For wholesale buyers, factory-direct pricing removes intermediary markups, and minimum order quantities for custom specifications are kept practical. OEM and ODM packaging services-including branded box design and labeling-are available on request. The 1157 LED turn signal bulb is stocked regularly for timely dispatch to fulfillment centers serving both online and retail channels. Standard inventory levels are maintained to support consistent lead times for this 1157 LED turn signal bulb across different order sizes.
