We cannot guarantee that the canbus led will fit all cars! Customers who are concerned about this, please place an order with caution. If you place an order, it means that you have understood and agreed to this statement. Due to the superpower 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 pairs of 50W 6 ohm resistors. Voltage: DC12V Current: about 1.75/0.25/0.75A [Measurement errors are normal] Power: about 21w (single contact),3w/9.5w (double contact) [Measurement errors are normal] Lumens: 2100LM Number of LEDs: 3014-144SMD Color: White/Red/Yellow(amber) Application: Car, motorcycle, truck, SUV, ATV, etc. Heat Dissipation Theory: Aviation aluminum 6063 Waterproof: IP68 Usage: Reverse lights, turn signal lights, and brake lights Features: 1. High efficiency and low power consumption 2. Environment-friendly and energy saving 3. Faster on/off response time and vibration resistant 4. With a long lifespan of up to 50,000 hours 5. With 3014-144SMD high-brightness LED, brighter than ordinary incandescent bulbs. 6.360 Degree Beam Angle design lights up every corner. 7. Easy to install, plug and play. Package includes: 2Pcs LED Bulbs 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.
