did you check to see what kind of voltage that light bar accepts? Idk if the 350x comes with a stock regulator like the 250r (im sure it does) so if the light bar accepts only dc voltage you should be okay but if it doesn't have a regulator and only accepts dc voltage you'll most likely have problems
