Both front side lights fail to light. The rear side lights are OK. The fuses are OK. Both bulbs are OK.

I have read somewhere that the side lights have a common earth connection failure of which would cause both lights to fail.

Please can someone explain to me where I can find this connection if it does exist.

If not any ideas of the cause welcome.

 

Sorry. Did the no brainer and tried new bulbs. Everything OK. That's what comes of assuming!
