For CANBUS declarations:
The bulb has canbus function and better compatibility, but there are still some cars (such as 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, etc.) will appear hyper flash or error or not work, it is recommended to buy a load resistor at the same time. 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 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.
