Truck maintenance in winter (and VII) Lights and oil

When we get the truck ready before starting a winter work day, we cannot forget to thoroughly check  all the electrical equipment, starting with the lights, an operation that should always be performed once a day. Check that there are no burnt or broken bulbs or lamps, that the headlights are aligned, that the side and rear lights work correctly  and that if the lighting is LED it also responds. Any deficiency that is detected must be corrected immediately, either by replacing a lamp if you have a spare or adjusting the height of the headlights, 

And finally, it is good to remember that in winter it is convenient that the truck uses a motor oil semi-synthetic or synthetic because their composition better withstand the lower temperatures than the type oils do ore.
