I also have 17 XLT & I have replaced the front dome light bulbs with LED. It's an easy process and makes a Hugh difference in interior brightness.
Using a very thin screwdriver, carefully begin prying the lens cover downwsrd. If you do not wish to change out the bulbs at this time, prying down the lens just a little will provide enough clearance to blow out the bug in question.
Check out the modified section for more info on changing to LED bulbs.
