If its its DRW over 80" required. If SRW, I don't know why manf. (or owners) put them on SRWs regardless of capacities, not required width wise. As to LED cab lights, a lot of the aftermarket cab lights are junk-in particular one popular brand. Condensation inside causeing failures-they leak between base an lense. They dont dim, they quit. Std bulb you can change, led fails you replace fixture. But they look cool. No more or less likely to leak into cab-thats all in installation.
I wouldnt add cab lights unless truck requires them or your removing from camper. I ended up putting a switch on our cab lights (and 3rd brake) to turn off when camper on (camper has ID lights)otherwise on our std cab the length of overhang is a very large orange glow.
