Thank you for your answer. If it's not 100% legal, will the cops notice at us? Will we be fined if the cops notice? My uncle has a Lexus GS 350, when he turn the headlight on, i can see the car (or him) can adjust the headlight unit to control the glare, that looks awesome :). Will the fog lights from a authorized toyota dealer be cheaper, or the aftermarket one? which one should we choose? If we buy the aftermarket one, will they give us any guarantee at all?
