Can You Put LED Bulbs in a 1993 BMW K1?

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 H4 low beams, as they see the most use. Adding a matching LED kit later will complete the look and ensure consistent lighting performance.
