My headlights were always , what I considered dim since I bought my car. Switching to halogens did not really improve the situation. I could leave my highbeams on and I did not seem to bother anyone. Plus, my car would not start when the lights were left on. I was loosing juice somewhere in the ignition circuit. My solution was to install a headlight relay to give my headlights direct power from the battery. The original headlight circuit activates the relay so everything seems to work like normal , my lights are much brighter and the car will start regardless if the headlights are left on.
