My question with LEDS there is no way of having the factory Yellow.. light out indicator working as factory spec ??.. I like the idea of this working with LED bulbs. there must be a way since many new cars have LED bulbs and have the bulb out indicator in the dash. unless remove the bulb and take a bulb with wires attached to it and stick in the back of cluster and have it wired to the harness in a way to fix the system bypassing it to another bulb prewired to a harness . years ago I had an old Mercury Cougar with empty spot in dash for door ajar in cluster (( which was an option )) and I stuck a bulb with a separate plug wired to the dome light which would light up when door was opened as long as dome light was on the door ajar worked ..so just a thought
