MCS Bulbs

68 products — part of all Bulbs

MCS bulbs span the full electrical spectrum of Harley-Davidson model history, from the classic 1936–1954 Springer-fork machines — including units converted to 12-volt systems — through to the 2002–2017 V-Rod family and the broad 2003–2025 run of Softail, Dyna, FLT Touring, and XL Sportster models fitted with centre-mounted taillights. That breadth reflects the MCS philosophy of carrying a deep inventory across every Harley-Davidson generation, so whether you are hunting a correct-voltage headlamp for a vintage restoration or a wedge-type indicator bulb for a modern flat-lens turn signal, MCS likely has the right fitment. Sourcing the correct replacement bulb matters more than it might seem — incorrect wattage affects voltage regulation on older Harley-Davidson electrical systems, and an ill-fitting base can cause intermittent faults that are difficult to diagnose. MCS takes the guesswork out of the process with model-specific listings that confirm compatibility before you order. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, offers the complete MCS bulb range for straightforward electrical sourcing across all Harley-Davidson eras.
