Socket : 1156 P21W BA15S 7506 R5W R10W 1156 PY21W BAU15S 7507 1157 P21/5W BAY15D 7528 T20 7440 W21W WY21W T20 7443 W21/5W T25 3157 P27/7W Features: 1.high quality 4014 LED 150SMD chip provides high brightness and low power consumption. 2.The bulb is equipped with a constant current regulator (IC) for more durability. 3.360-degree illumination,light fuller and more focused. Voltage: DC12V Power: 22w (single contact),3w/10w (double contact) Lumens: 3600LM Number of LEDs: 4014-150SMD Color: White/Red/Yellow(amber) Material: LED+glass Application: Car, motorcycle, truck, SUV, ATV, etc. Heat Dissipation Theory : Aviation aluminum 6063 Waterproof: IP67 System Lifespan:50000 hours Usage:Reverse lights,Turn Signal lights and Brake Lights Package: 2Pcs LED Bulbs Due to the super power of the bulb, it emits a lot of heat during operation, and can only be used for turn signals, reversing lights, and brake lights. It cannot be used for headlights, fog lights, daytime driving, etc. If you need to install 4 at the same time, very few cars will cause errors or super flash problems, please buy resistors together to solve the problem, 4 bulbs need 2 pair of 50W 6 ohm resistors. Note: This bulb is Canbus Error Free for 95%+ vechiles system, but the load resistor (decoder) may needed for some of the Europe and American Vechiles. For example: Volk *wagen, Me*cedes-B*nz, B*W, A*di, K*a, O*el, Re*ult, H*t, Lo*o, Sk*da, J*ep, D*dge, Ch*ysler, V*lvo, F*at, F*rd, S*at, Al*a R**eo and so on. The bulbs are equipped with Canbus, but there are still a few vehicles that may need to add an additional load resistance decoder to bypass the error code/flicker/not working issue. In the following cases, there is no problem with the bulb, if you mind please place an order with caution. 1. The bulb does not light up or the bulb is on for a while, then it goes out or the bulb flashes. 2. The dashboard displays an error code or the radio is disturbed. _x000D_
