    Question Need advice with E90 headlight LED bulbs

    Hello,

    I recently replaced my halogen headlight bulbs with LED bulbs. The outcome is totally worth the extra cost, however, the bulbs flicker every 3 to 5 minutes as long as the headlight switch is not on the off position.

    I'm not sure why this happens and don't know if it could be of any harm.

    Any advice ?

    You will need to add a resistor inline with each led bulb. You can now buy these resistors on line (e bay is a place to look.

    Hello,

    Thank you for your reply.

    I have already done it, the resistor is not responsible for this flickering.

    It was solved by coding out the warm/cold bulb checks.
