I swear this is the same guy who told me that new trucks never need repairs and i should go work for a good company with good equipment so i don't have to drive on US routes and can stick to Interstates. Remember that guy who said he would work for a good company that wouldnt send him out in extreme weather????
I love the "reflectors can be challenging to learn too". uh, if you cant figure out whar or where the lights and reflectors as, please dont drive.

There are all these special terms for lighting used in the High Road Training material but I would like to find some tutorial with pictures and diagrams that explains all these lights in detail. The High Road basically explains what is required by law in terms of lights.
How does one identify lights on the vehicle? What is their purpose?
I've heard the term "running lights" but I'm not sure of that meaning.
When I saw "identification" lights in the Training, I assumed they were the lamps that illuminate the license plates at night but I don't think so. I looked it up on Google and some sources claim that "identification lights", "marker lights" and "clearance lights" are one in the same. Is this true?
I would like to get to know each and every light on any truck I drive, how to turn them on or off and what their function and proper name is. There are a bunch of vehicle interior lights too. On cars, sometimes they have special names like dome light, vanity light, reading lamps and courtesy light. I call the ones on the dash to indicate trouble "idiot lights". Do truck interior lights have special names?
Some trucks have a "bubblegum machine" style light on top of the cab or two of them that are amber. What are those called and what are they used for?
Vehicle "light-ology" seems to be a branch of science all its own. Reflectors can be something of a challenge to learn about too.
