Ajovaloumpion jätisyys

Internet:in ihmeellisestä maailmasta löytyi tällainen:
The switch that can be found on some cars (i.e. the TF) does blank (!) of the beam
to prevent blinding upcoming traffic. However, it doesn't mirror/invert or switch
the beampattern in the other direction. It is like sticking those black patterns on the lenses.
It prevents the blinding but doesn't change the lights from RHD to LHD.

explained by ASCII

beam pattern of RHD \__\__ becomes __ __ instead of the LHD pattern: __/__/
Jos näin on, mahtaakohan kelvata täällä...
