Yes Dan is right, but the rule is wrong.

No, the rule is right. Vehicle safety equipment has to work according to objective technical prescriptions based on what level of every different aspect of performance is required to do an adequate job. Not according to your (or my, or some other guy's) idea of what "common sense" means or subjective impression of what "good enough" is. The reason why it has to be this way is because vehicle lighting components (and brakes, and tires, and just about every other safety-related vehicle component, system, and feature) affect not just the owner of the car but everyone sharing the road with the car. If I decide my subjective opinion (or "common sense") is a good enough basis for deciding the aftermarket lights I put on my car are good enough, but they do not provide at least the minimum objective performance necssary to do their job, it can and eventually will cause a crash involving people other than myself, and property other than my own. The same applies if I decide to manufacture and sell lights that look cool and don't provide the minimum necessary performance, but do look "good enough" to me and maybe to my customers who value "looks cool" more than "works well". This isn't government overreach, or overregulation, or anything like that. This is utterly basic to the nature of safety-related vehicle equipment.

Your invocation of the Constitution is faulty; you do a lot of things every day that the Constitution doesn't say you can do. Unless you are prepared to stop doing all of them, your argument about the Constitution falls flat on its face and pukes its guts on the dusty ground.
