Would you knowingly spend money on driving lights that increase glare? Regardless of brand or price... This is a big problem and not just cheaper lights but right through to $1500 plus.
The problem is driving lights that spike in the blue part of the spectrum. This can be dangerous, as it increases glare and is counterproductive for the very reason you are buying them. Note the task of driving at night is very specific and involves a complex neurological response. This is what many who defend LED verbatim seemingly forget. Distractive glare, compromised dark adaptation and driver fatigue are serious matters.
Glare is caused by light that is too bright or too concentrated. When light spikes in the blue part of the spectrum, it can be particularly blinding. This is because blue light has a shorter wavelength than other colours of light, and it scatters more easily. This means that blue light is more likely to reflect off of surfaces and into your eyes, causing glare.
If you are considering buying driving lights, be sure to ask for the spectral power distribution (SPD) of the specific light source. The SPD is a graph that shows the amount of light emitted at different wavelengths. A spike in the blue part of the spectrum is a red flag.
Don't be misled by marketing terms like "daylight", "friendlier" or "easier on the eye... etc." These marketing strategies are questionable at best. They do not change the laws of physics.
