Peugeot 407 Rear light cluster

[GerryS+No1]

Hi all, as a new member I'm sure that I'll be asking something already dealt with so a gentle prod in the right direction would be appreciated.
All the rear nearside lights (left hand drive) have stopped working on my 2008 Peugeot 407 SW. Everything else works fine, even the trailer lights except for the nearside indicator. After reading various posts I've done the BSI reboot and I understand that there are no fuses on that circuit to check so your help would appreciated. Modern electrics are not my strong point, in fact modern anything modern, this being only the second car I've ever bought new enough to have an OBD socket!
Gerry.

If all the lights have stopped working it may well be an earth problem. Have you removed the lamp unit to have a look at the connector & see if there is any signs of melting. Might be worth trying a temp earth to the unit. If thats ok maybe look at where the towbar is wired in.
