ANOTHER FIRST FOR SAAB!
FIRST CAR MANUFACTURER TO INTRODUCE A HEADLIGHT WIPE-WASH
to the motoring press
At the presentation Saab explained that to fully utilise modern, more effective headlights that were under development it was also considered important to be able to maintain the headlights in a clean condition during all driving conditions.
The motoring press considered the feature as being a major step in improving night-time driving visibility for motorists and improved general road safety for all road users.
Journalists from the MOTOR magazine praised Saabs engineers for their development work and indicated that SAAB would be a major contender for receiving the magazine’s annual Road Safety Award.

After intensive testing a system was chosen incorporating rectangular headlights, individual wiper blades and headlight washer fluid jets. The fluid was needed to keep the blades well lubricated and to dissolve road grime, dirt etc that otherwise impaired the headlights beam of light to the road ahead. The headlights wipers operated at a frequency of 40 wipes/minute and required the need for a larger 3 litre washer fluid reservoir.
The wiper blades were required to withstand 1,5 million sweeps across the headlight surface which corresponded to a service life of 120 000 km.
Removal of individual headlight assemblies and wiper blades etc was relatively easy due to most mechanical components being positioned and secured to the rear of the front grill assembly.
In due course the headlight washer system became incorporated with cleaning of the windscreen.
Some Interesting features of Saabs headlight cleaning design:
The wiper blades:
· - Return to a position where there is little chance of them becoming iced up.
· - Are protected from exterior forces that could damage the blades e.g. road grit etc
· - Easy to service.
· - The cleaned area of the headlight glass is 94 % of the total glass frontal area.
cleaning of both headlights - full photometric compliance according to
· - Embossed text to be on the inside of the glass to maximise cleaning.
· - The electric motor is positioned so as not to be damaged upon a light collision.
- The electric
motor circuit includes a safety fuse that blows upon the wipers becoming
For their design Saab was awarded a Gold medal by the Swedish Automobile Association.
