COMMON ISSUES THAT CAN ARISE IN YOUR BMW
HEADLIGHTS
2
The headlights are the eyes of your BMW.
3
Headlights are an essential safety system for
nighttime driving and visibility.
4
They require proper care to remain clear and
operational.
5
INSPECTING THE HEADLIGHT
Start by inspecting your headlights so that you
can-

• Determine the extent of any damage
• And how you are going to resolve it

6
If they have become hazy and not crisp, better
examine them under sunlight.
7
In case of extensive and irreparable damage,
seek BMW professional help.
8
Severely damaged headlights need to be replaced.
9
Look for scratches and abrasions that indicate
more serious issues.
10
If the headlight doesn't turn on at all,
the problem might be with the bulb or connecting
wire.
11
IDENTIFYING THE ISSUE
After washing the headlights, if they look shiny
and new, then it is safe to drive.
12
If not, you can look at these possible headlight
problems
13
HAZING
Headlights become hazy when

• The hard coat on them wears off
• The coating of soft polycarbonate gets exposed

14
Because of this, their surface starts absorbing
scratches and becomes hazy.
15
Their lens soon gets covered with dark yellow,
rough crusted surface.
16
YELLOWING
Headlights start losing their shine and becoming
yellowish when-

• Their hard coats thin out
• They lose adhesion to polycarbonate lenses

17

• Spectrum of the UV wavelength creates another
  repeating unit among the carbonic chain.
• This absorbs the blue light from the lens and
  gives a yellowish appearance to the headlights.

18
CRACKS AND PEELS
When the hard coat deteriorates, cracks appear in
the corners and the upper parts of the
headlights.
19

• You may also notice the hard coat flaking off.
• When the cracks develop deep in the lenses, you
  will need to get your headlights resurfaced or
  replaced.
