2005 CHEVROLET IMPALA high beam

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to re-adjust to the dark.
When you are faced with severe glare, as from a
driver who does not lower the high beams, or a
vehicle with misaimed headlamps, slow down a little.
Avoid staring directly into the approaching headlamps.Keep your windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as your headlamps should
be checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low-beam
headlamps may be necessary if it is difficult to see
the lane markers (for horizontal aim), or if oncoming
drivers ash their high-beam headlamps at you
(for vertical aim). If you believe your headlamps need
to be re-aimed, we recommend that you take your
vehicle to your dealer for service.
