feature 1.LED flash relay, excellent waterproof, plug and play, suitable to replace most standard 2 pin flash 2. Speed is adjustable, clockwise: slower, counterclockwise: faster, flashing frequency: 50 times/min to 200 times/min, allowing LED bulbs to flash at normal frequency 3. The flickering frequency of the turn signal can be adjusted, and advanced SMD technology is adopted, with automatic short-circuit protection, automatic overload protection, and reverse-connection automatic protection, which can make the bulb work more stably (without buzzer) 4. This turn signal flasher can fix LED bulb related turn signal flashing, easy to install, plug and play, suitable for most motorcycles 5. Maximum power: 42W, which means that the power of all LED bulbs must be lower than 42W, if it exceeds 42W, otherwise a load resistor may need to be installed parameter Specifications: Working Voltage: 12V Flashing frequency: 50C/m-200C/m Working power: 42W Switching power: 0.02A to 12A Operating temperature: -40C to +80C installation tips: 1. When installing, be sure to align the feet correctly, the function of the flasher cannot be realized if the feet are wrong. 2. If the four lights of the flasher are changed together, you need to unplug the turn indicator of the instrument panel. 3.B pin is input, L pin is output include 1*Turn signal flasher
