I don't know how LS or the builder installed the electrics, but if the wiring to the headlamps is too small gauge, you can cause a voltage drop to your headlights. That reduces the amount of voltage that reaches the lights and the result is a dimmer than normal lamp. If you install other lamps that may demand more current (higher wattage bulb) the voltage drop will be more, and that brighter light you were expecting to see may actually be dimmer than what you started with!

To get some sort of idea of what your voltage drop is, start the engine, turn on the lights, and measure the voltage at the battery posts.

Then move your meter leads to one of the head lamps and measure the voltage there. It will always be less than what you measured at the battery, but more than one volt difference might be cause to investigate further.
