Faulty offside parking/side light

[Ray5150]

I have an Elldis Autoquest 115 (2008/31k miles). Offside parking/side light switches off after a couple of seconds and ohms reading on bulb socket is very low (compared to nearside). I've checked the wiring and the two chassis mounted earth points at the rear and all seem o.k. Is there possibly other earth points located somewhere else that I'm unaware of or has anyone experienced similar problems, and possibly has an answer? I'm worried in case it's a fault with the BCM so I want to make sure I cover all possible options first.
Thanks
Ray

Check all on that side and also the numberplate bulbs. One on the wifes Peugeot car was out and the bcm turned the lot off. When replaced it was fine.

There should be a junction box/multi-plug near the rear of the base van chassis for joining the base van lighting system with the Motorhome rear lighting , if so , it would be worth checking , there may also be 2 x earthing points from the same section of wiring to the chassis either side of the rear spring.
