i was installing L.E.D dome lights in my car yesterday when the lights wouldn't trun on, but that was the least of my problem. As i was driving i noticed that the radio wouldn't turn on and when i was getting out of my car the door lights didnt turn on as well...could this be a fuse problem and what could have caused this?

 

Yes, sounds like a fuse issue. And more than likely you blew it while installing the LEDs.

 

so, if i replace the fuse and install the lights again..would it occur? or i'd have to see

 

The LEDs pull a lot less power that the regular bulbs. Install the bulbs and replace the fuse if it happens again. I assume you put the regular bulbs back in, correct?

Check to make sure you don't have any change in your lighter socket too. Just guessing on this one.
