Usage Tips:Features: Made of high quality material, and practical to use SMD 3014 LED lamp beads, small size and high brightness. material FPC circuit board, is flexible and bendable, and the circuit is integrated. Non- wide voltage constant current source design: LED car turn signal can work in small cars (AC12V-24). In- design: Plug and play without changing the circuit. Aluminum parts actively dissipate heat, and the heat dissipation effect is fast. Few solder joints, improve product quality. Applications: turn signal lights, reversing lights, brake lights, tail lights, indicator lights, parking lights, corner lights, side marker lights, external lighting, commonly used in cars, trucks, motorcycle, scooter, trailer, for RV, boat, marine Specification: Socket: 1157 Power: 21.36W Type: LED Model: 3014-144 Replace Inventory Bulbs: 1157 BAY15D Replacement Stock Bulb: 1016 1034 1142 1157 1157A 1178A 1196 2057 2057A 2357 2357A 2357NA 2397 3496 7528 94 Light color: Red Material:Aluminum alloy Size:about 2 x 5.5cm Package Contents: 2 x Turn Signal Bulb Only the above package content, other products are not included.
