It's hard to say. The factory crash bar has a sweep to it and is rather thick, so it already blocks a bit of direct ventilation to the AC condenser and radiator by extension. If the light is mounted above it the bar would sit rather high, not to mention the inner radiator shroud would have to be removed or heavily notched to clear each end. Also, the brackets at each end stick out a fair bit so it might be more like 34"+ across. Now with my SXTH crash bar AND the custom grille installed, I could run a 36" bar but I'd had to do something with the inner radiator shroud. My only concern would be mounting the light (as far as bracketing to the crash bar) and if it clears the Velossa Tech Big Mouth. But if it was a choice between the bar and the Big Mouth, I'd ditch the bug catcher.
If you're still using the stock grille, I wouldn't even bother. The light would be obscured by the thick, plastic grille while simultaneously trying to melt said plastic.
