Superior Performance: Sylvania LEDs are manufactured with bright, long-lasting, SMD LED bulbs and a thermal management system that extends life and increases performance.. May Require A Load Equalizer For Optimum Performance: To help prevent hyper flashing and bulb out warnings, it is suggested that a load equalizer or resistor be installed. See Sylvania's Load Equalizer product..
