i was planning on strapping two on the underside of my sliders (two for each side), pointing them down and out.[/QUOTE]
I have seen that tried before, I am no expert by any means, but straping them to the sliders (bottom side) isn't such a great idea. I have seen them ripped right off the sliders.
The sliders are there for a reason…protection and keeping the rocks away from your body panels. If you put the lights there, you are defeating the purpose of the sliders.
When I mount anything to the bottom of my truck, I always try to keep them above the "slider line" that way I know they should be protected under "normal situations"
Ignore the signature, I am still working on it!
