Part of the problem is they sold you blue coated bulbs. Halogens can be driven up to to something like 3,600 which is still yellowish and 4,000 is about ideal for maximum distance vision with a headlight for a human eye. Plus all the kiddies want white or blue so manufacturers put blue filters on them to make the light whiter. Its whiter light but the filter is just just reducing output by removing part of the spectrum so we cant see as far as with the same 100/80 that doesn't have the stupid blue coating.
