Shaded lights are getting me down At first I really liked the shaded headlights feature of my new 2010 Prius. The beam doesn't go high enough to bug other oncoming drivers, and that seemed to be a good thing.
What I'm noticing is that the shading is a problem on windy roads. It keeps the lights from projecting far enough to see what the road is doing, and means that I would ...

Re: Shaded lights are getting me down
// The OP is talking about headlight cutouts. The cutouts are baffles or optics that allow light to fall on the road but not into oncoming driver's eyes. They are there for just that reason, and altering them out of specification is dangerous, rude, and illegal. Have your dealer check yours and make sure they are properly ...

Re: Shaded lights are getting me down I've also noticed that visibility is very limited on descents of short fairly steep hills. While you can see very well going down, you may have little idea as to what lays ahead in the road where it flattens out (without the hi-beams). There is a rather definite line at which light ends and darkness begins; the effect of the abruptness is ...
Re: Shaded lights are getting me down The problem comes from new headlights being brighter and better. Old headlight designs were pretty bad about keeping light away from oncoming traffic, but it didn't matter as much since they weren't so bright. The new ones are brighter with sharper cutoffs. The brighter light means the shadows to the side seem even darker, so the effect is ...

The light is cut completely off at the top. This can be seen when I drive up to my garage door (which ...
Re: Shaded lights are getting me down The problem is that HID lamps generally need to stay on, so the
low-beam simply drops a shutter across the output to cut off
the top of it and avoid oncoming drivers' eye level. It only
sorta works, as curve and hill situations can still throw the
bulk of brightness right into where opposing traffic is and the
car has no way to ...

Re: Shaded lights are getting me down Thanks for everyone's replies, but I still would love an answer to: - Is this how all 2010s are? - Is this how they're required to be by law? - If not, how do I adjust it?
Re: Shaded lights are getting me down // Quote: Originally Posted by xvs It's not the sides I'm talking about, it's the top. <snip> Top or sides, my point is the same: the brightness of the lit areas make the dark areas appear even darker. If you start with dimmer lights, the dark areas appear not so dark. It has to do with the way human eyes adapt to light and dark. You can see this when you walk a trail at night...

Re: Shaded lights are getting me down Quote: Originally Posted by Jabber Years ago, I replaced my headlights with an aftermarket set of projectors. The cutoff line looked really odd.

This gives you a cut-off on the oncomming lane but lets the light...

Re: Shaded lights are getting me down I don't like the cutoff ... it's too low. I posted something asking how to adjust the height of the headlights but keep forgetting to actully do what was posted there. It's still light when I drive home from work so I don't drive at night often enough for it to REALLY bother me. But it's starting to get dark sooner so I may have to take a look to see if the height adjustment fixes...

Re: Shaded lights are getting me down The cutoff is a product of the projector style headlights. There is very little you can do about them short of actually cutting the metal inside the projector lamp and altering it. And that is NOT something you want to do. Years ago, I replaced my headlights with an aftermarket set of projectors. The cutoff line looked really odd. Like this \____ \____ . The left edges weren't cutoff. After putting...
