Products include: 2Pcs LED Light Blubs. Socket Type: 1156 BA15S P21W, 1156 BAU15S PY21W, 1157 BAY15D P21/5W, 7440 T20 W21W WY21W, 7443 W21/5W T20, 3156 P27W T25, 3157 P27/7W T25 For CANBUS statement: This light bulb is equipped with CANBUS function, 98% of the models will not have light bulb flickering or light off or instrument error. If the above problems occur, please add a canbus decoder to the bulb to solve the problem. If you mind this regulation, please order carefully, thank you. Feature: Voltage: DC 12V Power: 5W Lumens: 1500LM Number of LEDs: 3014-81SMD Color: White Application: Car, motorcycle, truck, SUV, ATV, etc. Heat Dissipation Theory: Aviation aluminum 6063 Waterproof: IP68 Usage:Reverse lights,turn signal lights and brake lights This light can only be used for turn signals, Reverse Light , brake light.Can not be used as headlights, fog lights, daytime running lights!!! LED car turn signal features: 1. 81SMD 3014 LED lamp bead, small size and high brightness; 2. New material FPC circuit board, the circuit board is soft and bendable, and the circuit is integrated. [The lamp body has glass cover protection]; 3. Non-polar wide voltage constant current source design: LED car turn signal can work in small car (DC 12V-24); 4. In-situ design: plug and light without changing the circuit; 5. The aluminum parts are actively dissipated, and the heat dissipation effect is fast; 6. Less solder joints to improve product quality if need install 4pcs at the same time, very few cars will cause error or hyper flash issue, please buy resistor together to solve the problem, 4pcs bulbs need 1pair 25W Resistors. NOTE: 1.If the bulb has a hyper flash or an error, please add a load resistor decoder. 2.With DC 12v power supply, it can be judged whether the bulb itself is working. 3.Please confirm your socket before making an order. Thank you.
