I have had true hid convertion in my scort since feb and if you've never driven at night with hid's you just don't know the difference. 9004 high/low kit places the bulb exactly where the normal 9004 hale does. to get high beam a solinoid pulled the bulb back and up the 3 millimeter and there you have it. i've never gotten flashed on the highway. and as for field of vision at night if you can tell me after driving a car with hids and then right after drive one without and tell me they're not safer i will gladly laugh. as for legality the bmw 5 series uses a hid that is rated at 6450 K and most hid kits on the market are 6000. any higher that the 6450 mark and your breaking DOT. there are also more and more kits out there that are DOT Approval. the sharp clean lines are because of projector housing. hid or hale they look the same on a wall. inconsiderite people do this ungrade and aim there lights high on purpose to maximize light coverage. with the correct aiming and kit you can run hid's safely and affectively with out blinding others. these lights are also easier on the eyes at night and decrease driver fatigue. All the major auto makers are using this new lightly source for the visability and safety factor not the look. i've said my peace thanx for reading.
