Yes, you need both to power both headlights - one cable powers one headlight.
Having a quick look inside one of my Carrera D132 cars, it seems the Carrera lighting system runs enough volts off the digital chip to power one white LED or two red LEDs in series. The different colour LEDs have different voltage requirements. In theory, you could use this info to re-wire your car with finer gauge wire and wire the two headlights in parallel from a single terminal on the chip. However that would require some slightly more than basic electronics knowledge and skills.
