Sorry, gotta disagree on that. Unless you are putting headlights with a higher wattage, the draw will be the same. Ohm's law, plan and simple. Amps = watts divided by volts. A 55 watt bulb operating on 12 volts will be 4.58 Amp draw.Yes, the halogens do use more power, so I would NOT use the halogen bulbs unless the relay conversion described above is in place.
The only big difference in halogen bulbs is there is halogen gas inside the bulb. That let's the tungsten filament get a little brighter and it also stays brighter longer because the tungsten doesn't boil off and stick to the inside of the bulb. That basically makes a mirror to reflect the light back. With the halogen, the tungsten doesn't do that. Basically the old, conventional headlights start getting dimmer from their first use. Halogen lights stay bright.
