Dual revolution lights

Has anyone tried the new dual revolution lights? They are made by a couple different companies. I was thinking about trying them out in my interior first.
I just want to know if the secondary color is bright enough? I was looking at the red and blue as auxiliary. I want to face them up onto the front of the stainless of my trailer, would look sweet lit up in blue. Then be able to flick a switch and change it back to red to avoid the fuzz at the scale house.

 

I haven't bought them yet. The chrome shop I saw them in still had them in the package. I mean I guess I could have asked the girl if I could take them out of the package and go run wires to them. I wanted to get some feedback from actual guys before I went through that. It's not like I need them ASAP. And of course the girl is telling me they are super bright, I just wasn't completly sold on them yet at 65$ per light. I'm pretty sure I can find them cheaper, just haven't found to many places that have them in stock. They are a fairly new concept, the blue lights I do have are under the truck to a separate switch so I can shut them off if need be. I think the dual revolution ones would be neat b/c I can put them in more places without a hassle from DOT.
