Further Confirmation: 1. What bulb size do I need for my vehicle? It depends on the original bulb installed. If you are unsure which bulb size fits your vehicle, please check your vehicle handbook or the part number on your original bulbs. You can also search "Automotive Bulb Guide" online.

1. I installed your bulbs, but they do not turn on. We highly recommend checking your fuses first. If they are good, put back the stock bulbs to see if they light up. If they do, we also suggest installing the bulbs with decoders before declaring the bulbs defective.

2. Why is the bulb flickering/dim or dashboard error message occurring? Some vehicles' computer systems cannot recognize the low power draw of the bulb, which may cause a bulb-out indicator on the dashboard and sometimes cause the bulb to flicker or dim. Installing a load resistor or CANbus decoder can solve this issue.

3. How do I know if my vehicle requires extra CANbus decoders?

4. The bulbs keep flashing when you try to switch them on.
5. The car's computer system keeps indicating an error.
6. The bulbs stay lit for a while even after you have switched them off.

7. The bulbs give off a dim light, unlike the bright throw of the bulbs.

8. How does a CANbus decoder work? In some sensitive cars, the bulbs fail to work because their power does not reach the minimum requirement of the installed CANbus system. The decoder not only increases the wattage but also sends a signal to the CANbus system of the car.
