I would like to add, that I was trying to do this on my 4.6is and I don't think that the actual clear piece comes off of the unit (once you get it down from the ceiling). Moreover, not all t10 led's will work in the dome light, in fact some are too big to install (in the middle section) and the others I put in the map light didn't work. I am not sure where to get ones that will work.
