A: Once again, materials come into play. HIDs are often in the 17-35 Watt range but they use a power transformer to fire them up like carbon arc. For my Jeep, I use Hellas with a 55/100W H4 light and upgraded wiring. If a vehicle came from the factory with the HIDs, then they are 50 state legal according to NHTSA. I find the full spectrum lights give better lighting as blue wavelength is too short for long distance vision unless the wattage is REALLY pumped up!

So you can't legally pull more power. The halogen lights are brighter because of the materials they're made with -- they pull no more power. It's technically illegal to run higher wattage lights on a street vehicle, but some people do. With the modern lights such as HIDs (also illegal in some states) and halogens, it's hard to tell if they are higher wattage than allowed. Unless you're blinding the cop coming toward you he's not likely to ticket you for to bright headlights! Unless you're running something like HIDs (obvious by the bluish glow) and they are illegal in your state. IIRC, four headlight systems use all four lights only on dim, so actually draw more power on dim than bright (55x4=220W; 18A@12V). When on high beam the inboard lights (dim only) go out (60x2=120W; 10A@12V). Of course placement of the filament in the bulb (reflector) and aiming has a great affect on lighting.
