Technical Info Turn Signals Connections: Most of the bikes use bi-metallic relays. Its frequency (which is the one that sets the pace of the turn signals) depend on the amperage circulating through the circuit. When replacing the turn signals from OEM to aftermarket ones which carry a difference power, consequently they vary the amperage circulation through the circuit that causes a change on the frequency of the turn signals rhythm. If otherwise, the motorcycle uses electronic relay (which frequency works independently from the amperage circulating through the circuit) the change of turn signals from OEM to aftermarket, should not affect the frequency of the turn signals rhythm. · Note: In case of doubt of what type of relay the motorcycle uses, we recommend to check the turn signal rhythm after switching form OEM to aftermarket.
