They will be MUCH better, and light up more road if you mount them in front of the truck instead of above the cab. Plus, you will get a lot of glare off your hood from those suckers up there... They are bright and not 'spot' ('pencil') beams, which are the only type of light I recommend for up on a roll bar above the cab.
Just fyi, so you have the best results! If they are just for looks, than fine... Mine get so little use, but maybe this weekend I will do a night run?!
