2005 Fleetwood Bounder 32w switch identify

That switch is to "flash" your upper running lights. best way to tell if its working is turn on your lights and have someone rock the switch while standing outside (in a moderaterly dark condition). You'll see your upper red running lights in the back and upper yellow/orange running lights in the front "flash" as the switch is rocked.

Depending on how its wired, your full headlights might need to be on. Plus there is also a possibility that your headlights will also flash, but I've heard that flashing your headlights is illegal in some states, so the switch might not be wired that way.
