I replaced the incandescent boot globe with LED no problem ( hard to know why it goes out without actually seeing it)I have tried placing an LED in boot and it kept going out. The two in the map lights work great. I would replace the LED it with the original light globe and the globe stays illuminated. No idea why, but frustrating. After several attempts and getting the same results I gave up on the idea of using a LED in the boot and replacing any other incandescent light globes. Though I would really love to get rid of those weak looking globes that are supposed to pass as DTRL's.
