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? Hi KHIEM, Aftermarket parts are almost always cheaper than genuine toyota parts. I would think that aftermarket brands would give a refund if their product is faulty just like any other general product.
