grill-mounted driving or fog lights

[w261w261]

I'm going to mount some driving and/or fog lights, and I don't like the stock location low and outside, so am going to put the lights in the grill. I took a look, and it appears that the horizontal grill pieces aren't that substantial. I was wondering about the possibility of the lights shaking after install. Could anyone who has mounted lights in the grill comment? Thx.
