E-BIKE Custom Parts This is an LED headlight with a built-in horn, specifically designed for e-bikes and electric bicycles using 36V-48V batteries, such as MATE, FLYFISH, SAME BIKE, and super73. If your bike originally has the light shown in the 10th photo, you can replace it directly. I have personally confirmed the electrical conductivity on my own bicycle. If you have a bicycle with a built-in horn, you can use the existing switch. It's a 3-pin connector for easy installation. The headlight body does not have terminals, so the wiring is handled by the individual, who is a bike enthusiast. If you are looking for perfection, please do not purchase. I cannot provide installation support or answer questions about compatibility, so please purchase only if you have the necessary knowledge. It's easy if you have a tester. Please confirm that your vehicle uses a 3-pin connector. The wiring configuration of the connector may vary depending on the vehicle, in which case you will need to rewire the connector yourself. Consider the possibility of having to redo the wiring. I have connected the wires with ultra-fine connectors and crimped them with tubes without soldering, so if you need to redo it, just cut the crimp tube and reconnect without cutting the wires. Please also be sure to check the male and female connectors. Please understand that I am not responsible for any defects that may occur upon arrival. Those who are able to rewire it themselves and succeed are happy, but those who cannot will complain, so I repeat, please do not purchase if you do not have the knowledge. #MATE #MATEX #MATEBIKE #FLYFISH #SAME BIKE #super73 #e bike
