My '94 had such weak lights that I'd check them just to see if they were even on when I hit the highway at night. My mechanic fixed the problem. There was a definate power drain somewhere in the circuit. So, he hot-wired the lights to the charging system. He rerouted the lights away from the dash switch and simply created a hot-wired configuration that feeds the lights directly from the charging system. The headlamp switch now simply operates a relay switch to open and shut the new hot-wired configuration. My headlights work like new now. It was a neat trick!
