I think UK rear fog lights are red and don't see it being otherwise - red and white lights do tell you which way the vehicle is facing. I think the reversing lights are usually switched by the gear selector and would need a rewire to do that but Ladas hey... (not that they were all bad, when in N Wales, a local taxi firm (before oddly, switching to Mercs) ran them for years and I can't see that if Ladas didn't have some reliability)
