Replace the stock relays and eliminate the need for load resistors with this solid-state design that provides consistent flash rate regardless of load. They work great with L.E.D. replacement bulbs, custom L.E.D. turn signals, or incandescent bulbs.Max load is 200 wattsAvailable with common 3-pin connector, or spade terminal for custom applications on motorcycles, trucks or carsEasy alternative to wiring in load equalizers
