A. Boslla LED bulbs are working between 9 to 16V, but the Daytime Running light works on about 7V. So it is not recommended to install on the daytime running light because it may have a flickering with an error on the dashboard, or can't turn on.

If your vehicle's headlight bulbs have a DRL function, please ensure you turn the DRL function off and only use the headlights in the "on" position.

B. To fix the problem, you can add our capacitor/resistor to check. But we can not 100% guarantee it works.

A. The capacitor or resistor Canbus is necessary if it shows an error on the dashboard when removing the original halogen bulb.

B. If encountering the situation that the bulb does not work suddenly but works well again after turning off the power and restart it, please consider changing the dust cover with more space for heat dissipation.
