The bulb will be easy to reach from the back side...gently turn the housing left or right and it will come out...remove the bulb....there are replacement bulbs that are brighter, and come in different colors...I can look for replacement numbers and sites for you if you would like...my suggestion it to wait until you are ready to install your interior lighting...WORK SMART NOT HARD
As for your other queries I have a friend that has strobes in place of high beams and in his trunk area plus red leds all over the place his is black sand though....I never really thought about the flint mica and color combinations that would look good...mine is white so my daughter chose purple and that is what I run...cold cathodes for the interior right now and multi color leds for the license plate....
