anyone here ever have a flex led wheel well kit form walmart ? Im Thinking about gtting on and converting it to a underbody kit ? think it would show enough there is 4 24inch strips ...

More than likely not. First off, the light output would be nowhere near that of an actual underbody kit. Second of all, the light that it did put out wouldn't diffuse very far out between the car and the ground. Those 24 inch strips might put 26 or so inches of light down, and probably only a few inches thick at best. Think how ridiculous that would look, especially on the sides. You're MUCH better off just getting an LED underbody kit. It would look tons better.

but why spend money when you can cheap mod at walmart
