B3 one chappalang also,Steering wheel got 2 design.Power
Switch/start button also two type..
The steering wheel and switch design is just a design change
from MAN. All the new MAN Truck and Bus will have this standardised
design. In fact, MAN Trucks changed to this design way much
earlier.
As for fog lights, it is meant for low visibility use like
foggy/hazy or heavy rain situations. To be used together with main
low beam. The idea of fog lights is to increase the vehicle's
visibility to those in front and oncoming, yet does not blind them.
In another words, there is no specific direction for fog lights, it
is just a simple bulb for everyone to see.
Low beam, on the other hand, is directional and it is meant to
illuminate the road directly in front of you, without blinding the
front and oncoming vehicle. Which is why RHD and LHD low beam has a
different beam pattern. Whilst the front and oncoming vehicles are
able to see low beam when it is clear, during low visibility
situations, low beam is actually inadequate.
But yeah, it is useless in SG, there's no fog, there's no haze,
there's no heavy rain. It is also illegal to install after market
fog lights as it is impossible for a chance to meet low visibility
situations.
BTW, it is not a regulation under ECE to have front fog lamps,
but it is a must to have rear fog lamps.
