these are a set of super bright cab lights
we use a switchback strip in each light
the white is super bright and the amber is just as bright
you can hook them up to just white or you can hook them up to the switch back function to where it white while your driving and it will blink amber when you turn your blinker on. your choice or you can just keep it on amber.
