I asked NYTOP about that, and they said it was the OEM running board lighting, which you can opt to leave it off the vehicle for off-road usage. You'd have that issue with any flat rock slider like this. I'm not even sure the OT+ has one (I need to look under mine which now has the running boards, just got it yesterday!). If it does, and I want to keep it, I'll move it inboard and up. It will keep some lighting, but be out of the way.
Hi, in addition to my answer about the OEM lights, FWIW NYTOP told me that "Our GX550 sliders are designed to provide about 6 inches of stepping surface. Almost as wide as the factory plastic side steps." They also said in response to my question about using them as a lift/jack point: " Yes you can definitely jack up the vehicle on the sliders if needed. They are designed to be able to fully support the weight of the vehicle." Again FWIW with respect to strength/etc.
Hi, one more piece of info from NYTOP. when I asked about strength in general, they said "Our sliders are made with 1/4 inch steel sheet metal on all weight-bearing surfaces. Our sliders also have internal ribs that are welded within that you can’t see from outside, for extra reinforcement." I checked around some and it looks like that thickness of steel would be considered relatively beefy. FWIW.
I checked and my OT+ has a light as well, looks like it shines out on top of the running board at the passenger doors.
