Can LED Headlights Increase EV Range?

From News Coulomb.

While I was installing a set of LED headlights to replace the 20+ year old halogen headlights in my Ford Ranger Electric, I thought I would discuss just how much range an EV can gain by using LED instead of halogen headlights. The numbers might surprise some people, especially given the overall difference in energy consumed by LED versus halogen headlights.

*spoiler* It’s not much.

The original halogen headlights in the Ranger EV would pull about 60 watts each, while the replacement LED headlights pull about half that. At a constant 45 mph, the Ranger EV will consume about 250 Wh/mi, so after an hour of driving, it will have drawn about 11.25 kWh. If these LEDs pull half the wattage of the halogen bulbs, after that same hour, they will have saved 60 Wh. So the overall difference in consumption will be 11.19 kWh to travel 45 miles, or 248.7 Wh/mi. Basically, the energy consumption difference will be a rounding error.
