Purpose of cab lights?

[8secondride]

What do cab lights do? Only thing I can guess is help you check and see if you have overhead clearance to fit under something. Not a dig against the lights, I think the look good on most trucks.

because the DOT requires them on duallys and other large trucks

Why on a SRW ? because I want to be seen even just coming up over a hill as soon as possible

i have been told that cab lights help with the glare of oncoming cars but not sure on that plus now i think its a personal preferance and for looks

Cab lights purpose is to indicate the width of your vehicle, vehicle/trailer combo. If you are over a certain width you need the lights to indicate such. (I think it is 101 inches but not sure)

Most "box type" trailers, enclosed, travel trailers, etc have the lights on them. The purpose of putting them on the cab is so when your pulling something like a flatbed trailer you are still indicating width from the front.

Most trailers have it on the rear no matter what (three red center, one left, one right; running lights)

Putting it on the cab allows you to pretty much pull anything, as long as your vehicle is rated for the wieght.

Only if the vehicle was ordered with them (it is an option of the f250's and f350 SRW vehicles) or someone added them afterwards. But they are not mandated by FMVSS 108 on the SRW vehicles.

80 inches or more is the magic number for trucks & trailers.
