As others have mentioned I have replaced almost all the interior bulbs in the RV and the house with LEDs. Only a couple have failed, those due to mechanical problems that caused the connections to the LEDs to fail, the LEDs themselves did not fail.
I replaced the outside RV light with a rather dim bulb since we usually don't sit around outside at night, but it helps us find our way back when we go out at night without bothering our neighbors.
Oh yeah, I bought almost all the RV LEDs at eBay, most for the house at Costco.
