The light pattern does not need to be adjusted. The headlamp pattern is designed in such a way that oncoming traffic is not dazzled.
The headlamp pattern for halogen headlamps is readjusted by masking the headlamp lens. The headlamp pattern may not be as good.
Masking the headlamps
Copy the A and B templates for left-hand drive cars or the C and D templates for right-hand drive cars, see later section "Templates for halogen headlamps". The printed owner's manual describes how the templates can be made in the correct scale:
- A = LHD Right (left-hand drive, right lens)
- B = LHD Left (left-hand drive, left lens)
- C = RHD Right (right-hand drive, right lens)
- D = RHD Left (right-hand drive, left lens)
Transfer the template to a self-adhesive waterproof material and cut it out.
Start from the design lines on the headlamp lenses; see the lines in the following figure. Position the self-adhesive templates at the design lines with the help of the illustration.
Upper row: left-hand drive cars, templates A and B. Lower row: right-hand drive cars, templates C and D.
