The dipped lights on 307 Peugeot have stopped working and one of them makes buzzing noise when I turned lights on, parking lights and full bean working fine,any ideas as bulbs look fine and chances of 2 blowing same time unlikely,
I have a 04 407. One dipped light went last week and had the same issues as you. Rather than replacing just the one bulb I replaced both. problem solved. No more issues. Keep good buld as spare just in case. Also noticed that when one bulb blew I was getting error messages for the ABS and Air bag. Was thinking it was going to be an electrical nightmare but since replacing both bulbs no more warning indicators.
