Please Note: Tests carried out by the Company show that some common vehicles present so far insoluble problems when coupled to a trailer with LED lights. This may take the form of the hazard warning lights flashing continuously and there may be other problems too. Many other vehicles perform faultlessly when connected to LED equipped trailers. However, where such problems do occur, these are vehicle problems and Ifor Williams will not be responsible for their resolution. Owners are strongly advised to make thorough checks with the vehicle manufacturer before buying or specifying LED trailer lights.
