Only 100,000 on and off cycles? How about the blinking LEDs on the networking devices? They probably go on and off multiple times a second, and I've never seen one burned out before the device itself went bad.
When we talk about the puddle light on a Tesla, the LED is probably just a Light Emission Diode itself fed by DC power from the car. On the other hand, the LED light bulbs include the diode and the driver circuit to convert 120V AC into DC for the diode. The LED light bulbs' lifespan and cycles are mostly bounded by the driver. For the LED diodes themselves, the biggest enemy for their lifespan is over driving them with high current to force them emit more lights.
