If the solenoid is mounted in a favorable position (more direct wire runs) and a heavier gauge wire is used, there will be less resistance to the electrical flow and the lights, getting more voltage, will be brighter. This can be a help if there is a problem (corrosion, marginal connections, etc.) with the original wiring. In most cases, if the original wiring is in good shape, there will not a significant improvement. My '51, which was well-maintained and stored under good conditions previous to my ownership, has bright, white headlights on 6 volts.
Remember that under normal circumstances, the power for the headlights goes through the switch on the dash which adds length and extra connections to the circuit. A solenoid eliminates all of that.
