Below is a post that best describes my lights. I don't have navigation. What would the HID conversion do? Is that basically changing to a different light bulb?
Do Your New Projector-Type Headlights Fail to Provide Adequate Light On Dark & Undulating Roads?
Do you have a newer model car with headlights that fail to safely illuminate the road? Do you experience what appears to be a black curtain painted across the upper half of your windshield? Do you find that you can’t see road signs above a certain height or that when you turn into an unlit driveway you cannot see where you are turning? Have you noticed that oncoming cars frequently flash their lights at you and you’re momentarily blinded by an intense light glare?
Many newer model cars today are being made with projector headlights. These projector headlights are different than older models’ standard headlights that had separate high beam and low beam light sources. Projector headlights are lit by a single filament at one focus of an ellipsoidal reflector with a condenser lens in front of the lamp. Between the reflector and the lens there is a shade that provides a cutoff of all light above the center of the light bulb so that, theoretically, the low beams will not blind on-coming drivers with the intense high beam. The shape and sharpness of the cutoff is determined by the shade’s position in the optical system and the shape of the shade’s edge. When the driver turns on the projector’s high beam, the shade is lifted up and removed allowing all the intense light to escape without any cutoff. The high beam from a projector headlight is a very bright and produces a strong glare that can be blinding to oncoming drivers.
Many drivers are now noticing that one significant problem with projector headlights on the low beam setting is that the cut-off line of the light moves when the car hits bumps in the road, accelerates, decelerates, and when climbing or going down a slope in the road. Frequently, drivers now see what appears to be oncoming cars with projector headlights “quickly flashing their brights;” however, in reality the on-coming car has only hit a bump in the road surface causing the cut-off of light to momentarily shift upward exposing a bright burst of the high intensity light. This apparent flashing of the high beams can be really annoying; however, a greater safety concern is that the projector headlights’ cut-off of light moves when the car is going up or down a slope or carrying a heavy load in the back of the vehicle. While going down a slope the projector’s cut-off of light shifts downward and the headlight’s beam distance is significantly diminished out in front of the car (headlights appear to be driven down into the road surface). Obviously, this creates a safety issue because the driver cannot see pedestrians and animals out in front of the car to allow adequate and safe stopping distances. Additionally, road safety signs cannot be read on undulating roads because they are not illuminated since the beam of light is being driven down on the down-slopes. Likewise, when a driver is driving up a grade the projector’s cut-off of light shifts up further than it would on a flat road and more of the high beam intense light is unintentionally directed into the eyes of oncoming traffic. Both of these two unintended consequences of projector headlights can lead to extremely dangerous driving conditions for drivers .
