Because jeep interior lighting really sucks...as does most interior lighting in many vehicles. LED lighting (for me anyway) is a lot more brighter, and not so yellowish.
But to answer the OP, try putting the original bulb back into the dome light. If you replaced it with an LED and the the LED was not designed for a CANBUS system than that is why you are having problems. You need to put a CANBUS compatible LED in the dome light...Krautoled
is one place that you can get the correct led.
If you already do have the correct led, than it is possible the bulb went bad and is causing your problem.
