Product information: Model: 1156 (single contact), 1157 (double contact) Base: BA15S (single point); BAY15D (high and low points of both feet) Light source: COB Voltage: 12V Color: white Voltage: 12V DC (output voltage of ordinary cars) Features: Light source: LED belongs to semiconductor solid light source, which is vibration resistant, waterproof, and high luminous efficiency, and belongs to green light source. The European automotive industry already has a mandatory standard to use LED as the vehicle light source. Energy saving: 1/10 of the energy consumption of traditional halogen lamps, which can better protect the automobile circuit. Long service life: the service life is up to 50000 hours, and the traditional bulb does not exceed 2000 hours. Fast startup: LED does not need hot startup time, and the response speed of lighting is fast (nanosecond), which is suitable for objects with fast moving speed. Installation precautions: replace the original traditional glass bulb directly without modifying the circuit. Note that the original bulb is very hot. Please be careful when replacing it! LED has positive and negative poles. If it is not lit, change the direction (that is, change the electrode). Detailed description: 1. It can be used as steering light, brake light, rear fog light, reversing light and tail light. 2. The model is the same as that of the original vehicle, and the bulb of the original vehicle can be replaced directly without changing the circuit. 3. No delay in lighting, fast response time. No filament structure, the vehicle control circuit is not easy to oxidize, and the service life can reach 30000-50000 hours. 4. Low energy consumption, high brightness and higher cost performance. 5. Rich color, pure color, optional DIY, highlight personalized lighting. 6. Cold light source, with good comfort, belongs to green environmental light source. Packing list: Automobile lamp * 1
