I recently upgraded to H4 LEDs for my headlights as it has made a considerable difference in night driving, so i decided to do the same for the daytime running lights. I did this just so the colour matches, as the LED headlights are white but the daytime running lights are yellow.
The LEDs for the daytime running lights are an exact copy of the old lights i.e. 12 volt, twin filament, bayonet type mount etc. The guys at Autobarn helped me with sourcing them. The only difference is that they are LEDs.
Now, for some reason after installing them correctly they don't run? Whether the light switch is on '0' or low beam - they don't light up at all.
Any ideas?
