I need to replace my headlamps due to the lenses being hazed (I'm not interested in polishing them) and am wondering if the clear lens 2002 and newer headlamps will install seamlessly on my 2000 truck. This seems desirable to me due to the obviously brighter lamps on the 2002 and newer trucks. Not to mention that I read KLHansen say the same thing about the improved 2002 lamps. I'm also not interested in any non-DOT approved HID upgrade. Thanks for any and all replies.
