My 93.5 G20 has the RH headlamp much dimmer than the LH. I had the same problem on my 92 NX, and it was the Headlamp Switch, so I bought one for the G, but I still have the problem. I replaced the bulbs, and even swapped them back and forth. Someone HAS replaced the sockets on both sides, so my next thing to try is to SOLDER the wires and make sure I have good connections. I swapped the fuses even......anyone have anything else to try?
