Some things about the article don't make any sense to me. First, why would someone use led headlights (which would involve the extremely careful removal of the phosphor from the led junction to preserve the uv generating capability of the led), just to end up with something that could be replaced with grow bulbs?
Second, why are police stopping people with range rovers to check if their headlights are "legitimate"? How would that deter a crime like headlight stealing? Doesn't that just punish individuals for having aftermarket headlamps?
It's not clear to me that the police response is appropriate...in fact it seems completely disjoint from the crime.
