Reduce headlight glare with band-stop filter

I was throwing around an idea for a science project: Testing the effect of optical band-stop filters on headlight glare during night-driving. Perhaps by analysing spectrums of headlights, you could tune a filter to selectively block those wavelengths. Does this make sense?

It appears optical band-stop filters are available for Raman Spectroscopy, and anti-laser glasses. Very expensive. If headlights turn out to be broad-spectrum, or vary significantly from model-to-model, this won't work. What do y'all think? Unlike the filters, cheap spectrometers are available on Amazon.
