It features an extensive lighting system powered by a halogen-based setup where a single 9003 LED dual-filament bulb handles both low and high beam duties within the same reflector. This model belongs to the late years of the Cooper's 2002-2020 production span.

Can You Put LED Bulbs in a 2018 MINI Cooper?

Upgrading to LED is one of the most effective ways to modernize your MINI's appearance and safety profile. Since your Cooper uses a single 9003 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the 921 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
