93/94 have the BEST lights on any vehicle I have ever come across. They are very waterproof and seem to last well and light up well and the harnesses are simple with just bullet connectors. It makes sense as Rover bought them from a company that made lights for commercial trucks. Rubolite which is now owned by trucklight (or lite, I forget). 95/97 are the WORST I have ever come across. The harnesss are one part with the main harness and the connectors are not commonly available and repair kits for the harness are expensive when you can find them and they are not waterproof in the least (side markers use o-rings, front and rear lights use foam discs) so they corrode and stop working.
