Led trailer lights in Maintenance Posted February 6, 2011 · Report reply Hi guys, I am very new to bmw's having purchased my first one only ten days ago. Details. 2009 X5 E70 Twin turbo diesel The vehicle came with a towbar fitted, included was a unit that needs to be used when towing a trailer with led lights. I have tried this but have found that the park lights stayed on continuosly. Took it to my autosparkie and cut the hot wire and thought he had solved the problem but we now have no brake lights but all others work .( He also fitted a tekonsha prodigy electric brake unit). Have since been I the car with no trailer and have a warning message : left hand trailer light fault. This trailer has prevously worked fine on all other cars. Any suggestions ?
