Hi. Newbie here. The front light on scooter was only high beam. Got a replacement bulb. The same specs as the one I took out. (12v 35/35 from Halfords. UK). A bit of fiddling it worked. Less than a week later, now it doesn't. The only thing that works is the passing switch. I have checked the fuses. Cleaned the contacts. Still nothing. Any help gratefully received.
