My amber light is dim on both de frogger and fog light switches , for what’s that worth.

To keep things simple, I think I'm going to use the rocker switch without the indicator light.....one less thing to try and figure out 5 years from now when things stop working for whatever reason.  I tested everything indoors in a dimly lit room.....ya know, I originally thought that amber light was an LED but now I'm not so sure....may just be a light pipe utilizing a tiny incandescent bulb, like the bulb for the one nearby to help you find the switch on the dash at night.
