I wasn't referring to cars but so be it . So there's a way to have brighter lights for the driver but no one else will will be able to notice ? Great trick . I would suspect that most of your offenders are not using dot approved bulbs , not using the approved output , nor taking any time to adjust the headlights ( this is possible ) . You can buy high output halogens that are not approved for road use . A good majority of the new vehicles with led's are just as annoying as are the genius's that feel their driving lights need to be activated in perfect weather .
