Re: Educate me: What is the pupose of cab roof marker lights?

Federal law requires them on vehicles greater than 80" wide along with additional red rear lights. I'm not sure why people order them on SRW pickups. Truck with snowplow greater than 80" or one that frequently carries loads greater than 80"? Maybe just the supposedly big truck "cool factor".
