Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that LED headlights are more energy-efficient than halogen headlights?

Yes. A peer-reviewed automotive study states LED headlights have clear energy-consumption advantages over traditional halogen headlights, and a lamp test measured LED headlamps drawing far less current than halogen. Other sources only note LEDs' low power use or their adoption in headlamps without a direct comparison.
