You may have two independent problems. I just replaced my porch light bulb and the old ones filiment looked fine as well. If you want to try, swap out a bulb from one of your bottom compartments.
As for the grab handle light, just so that we are all on the same page, it is controlled by the "aisle light" switch, not the "porch" switch. By turning on your aisle lights, that turns on the grab handle outside. So if your aisle lights are coming on inside the coach but the grab handle isn't then it would be an issue with the LED in the handle.
