so they can be seen.
So they can feel like truckdrivers.

So that the people trying to jump over the vehicle (at night) can see that it’s tall and that they’re not gonna make it over.
so you can see them better
because in the night time those lights help other people on the next side of the road so they wont crash
Those trucks are designed for off road use and they usually use those lights to get a better view of the road, to hunt and even to drive through the rain. Nowadays it’s just for looks — most of the time.
I think that this is because most people go off road with bigger trucks and they need to see more than a normal truck on the road.
the lights are called marker lights or clearance light and on a big rig dot mandates that they are there. they are for you to be able to see if you can clear an object in height.
They are called clearance lights and they are to see if the vehicle will clear an over pass or other object, but they also help to identify the vehicle as a semi or a pick up. On semi’s the trailers are usually taller then the trucks so this identifies the unit as being a box trailer instead of a flatbead.
those are clearance lights. you can put them on any truck.
There are all kinds of regulations for lighting on large vehicles. Trailers over a certain width have to have 3 lights in the back not including the brake and turn signals, over a certain length they need to have lights on the side too.
Trucks over a certain GVW need to have the lights on top you asked about. All of these rules are for safety. Other drivers can see these trucks at night.
because they are a bigger class of pickup versus 1/2 ton pick ups and such. On standard beds I believe they are an option. Dualies come standard with them front and rear (5 amber roof, 5 red rear usually 3 in middle and 1 on each bed flare)
