For polar inverterA practical and reliable polarity converter, negative to positive, positive to negative, can be used in various automobiles. Even if the negative pole is connected, the decoder will not burn out and the quality is stable. Excellent performance - The negative decoder has an effective interference absorption circuit, which can reduce the interference pulse of the reactor to less than 1/10 of the original pulse, thus eliminating interference from the reactor that controls the computer.Excellent function suitable for the resolution of most modified headlights, the lights are not bright, cannot be adjusted and the dimmer is overheated. Even if there is a problem with LED headlights, you don't have to worry about the lights not lighting up, and the safety and reliability will be greatly improved.High quality negative switch ----The polarity converter is made of selected aluminum alloy, corrosion resistant, rust-proof, anti-aging, not easy to wear, good compression resistance, good heat dissipation function and long service life. .Professional manufacturing - each of our products has been carefully designed and manufactured.
