About This 【5X Brighter Than Halogen】Each 3157 LED bulb is equipped with 48 high-brightness chips and a projection lens, achieving 360°full-angle illumination. When changing lanes or braking, it clearly alerts others even in harsh weather like dense fog, creating a safer driving environment. Lumen: 720LM, Color Temperature: 6300K. 【Energy-Efficient & Long-Lasting】The Yorkim 3156 LED bulb operates at just 4.2W—only 1/4 the energy consumption of stock bulbs—while delivering 5X brighter light. Built with aviation-grade aluminum for superior heat dissipation, it lasts over 50,000 hours, making it an ideal upgrade for automotive lighting. 【98% Vehicle Compatibility】Featuring the latest intelligent integrated circuit driver, this daytime running light fits most vehicles. Note: For rare vehicles with unusual CAN bus systems or installation issues, a 50W 6Ω load resistor may be needed to prevent hyper-flashing or error codes. 【5-Minute Plug-and-Play Installation】Our parking lights feature a non-polarity design—no wiring modifications or polarity adjustments needed. They fit standard bases (not compatible with CK-type sockets). Even beginners can install them in 5 minutes, with instant-on functionality (no warm-up delay). 【Wide Fitment】These reverse light bulbs directly replace 3157/3156 models and work for backup lights, tail lights, etc. Compatible with socket models: 3056, 3356, 3456, 4156, 3047, and more. 【Worry-Free Support】Due to diverse automotive electrical systems, rare compatibility issues (e.g., missing colors, no light, or turn signal errors) may occur in a tiny fraction of vehicles. Most issues are resolved by adding a load resistor. Contact us via Amazon buyer messages for troubleshooting help or replacement—we’re here to assist!
