Federal signal is just as good as whelen if not better. As for the hideaways, grommet or the screw in style both work. The screw in style can handle 20+watts as well. Grommet style are only recommended for 15 watts. Just put a light ring of silicone around the rear of the installed lighthead. If you use amp connectors silicone those up as well. I recommend uni bits over the hole saws when drilling into the lights.
