Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old H7 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: BMW vehicles use a CANbus system, so LED replacements may need an anti-flicker decoder. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

Are LED headlights legal for a 2014 BMW M235i?

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state.

For the best legal compliance, choose a DOT-approved H7 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

How much does it cost to replace 2014 BMW M235i headlights?

A pair of halogen H7 LED bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

Use a CANbus decoder.

Can You Put LED Bulbs in a 2014 BMW M235i?

Upgrading to LED is one of the most effective ways to modernize your BMW's appearance and safety profile. We recommend starting your upgrade with the H7 LED low beams, as they see the most use. Adding a matching H15 LED LED kit later will complete the look and ensure consistent lighting performance. Because BMW utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the H8 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
