Must have motorcycle LED lights for highway bars/crash bars. Each LED chip is dual color for the switchback function; a nice pure white for driving lights and a bright amber for your turn signals. When you hit your turn signal, the driving lights on the corresponding side will turn completely off between amber cycles for maximum visibility. Built with the highest quality zinc and a premium chrome-plated finish, they are guaranteed to last. The low-profile design allows for an OEM like appearance on most 1 1/4 in. highway bars.
