Ok. I know some people have DAB reception issues after fitting variousl headlight upgrades, but I have a weird one...
My THQ V3 (all black) headlights have the THQ led H7 and H1 bulbs fitted. When only the drls are lit I get very poor (zero) DAB signal, but when I switch on the lights, I suddenly get ok DAB reception! Now that my commute is in the daylight I can't listen to 6music anymore (was fine over winter as it was dark and the headlights were on!)
I'm pretty sure the drls stay on when the dipped headlights are on, so why would turning on the lights improve the DAB signal? I've tried fitting ferrites to a number of the wires at the back of the headlight but this didn't seem to make any difference.
