Check if your motor is maintaining the battery voltage at 13.8volt or 14.4volt. Some cars can be altered from one to the other using a lap-top plugged in the car's diagnostic socket to access the charge-controller in the control micro. With tungsten-filament lamps, there is a big brightness difference between the two. This is because the light creating efficiency of (nowadays) halogen filled quartz enveloped tungsten filaments shoots up remarkably with operating temperature and operating voltage, as does the whiteness (due to better blue end). This doesn't apply anything like the same with xenon discharge lamps operated by a high-frequency converter often mistakenly called the ballast, or white LED.,whose light is produced from fluorescent powder excited by an ultra-violet LED.
If your problem is poor headlight brightness, check with an accurate digital voltmeter the battery voltage while engine/alternator are running. If it is only 13.8volt, you can convert it easily with very minimal cost with my mod. involving an resistive alteration to the cold battery sensor under the battery carrier. If my memory serves me, it's a 33K0 half watt in series with the brown lead. Such resistors can be had from Maplins or Radiospares. Simply cutting the brown lead will only lift the charge voltage to 14volt, you'll hardly notice that.
