Very bright in both modes. About the same in brightness as it is when it is amber. We do not sell switches but it can be put on any switch. You can pickup nice switches that can be installed in a panel at lowes or home depot or even a radio shack if you still have one in your area. Here is a link to something that will work for the auxiliary switch https://www.amazon.com/Gardner-Bender... Thanks!
