I bought Philips DRL's [1284WLVWAC1"]]/ LED DayLight 2.8"]] and had them fitted professionally. Lights come on correctly but after 3/4 minutes switch off. Tested voltage and it is correct. Lights dim on sidelights but only illuminate when engine is restarted to begin cycle again. This fault is exactly the same for a new control unit.
Can anyone give me an indication of what is causing the problem? The auto electrician is as puzzled as I am.
