if you are going to use LED bulbs, you need to make certain that they are CANBUSS bulbs (those unfortunately are not all the same, but i have had excellent luck with bulbs from superbrightleds.com). i have used canbuss bulbs to replace the interior "dome" lighting, the trunk light (i have an srt6 roadster), the glove box light and bought the license plate mercedes lamp replacements (there are 2 license plate lights) that you can find information about here with a thread search (sorry i don't have the link). i haven't had any problems with the LED bulbs i purchased. non CANBUSS bulbs do not have a built in resistor (in simple terms) and will indicate a bulb out dash warning light more likely than not. the basics are that LED bulbs draw much less amperage than standard bulbs so they create a false bulb out indication to the system, hence the bulb out indicator on the dash.i have a pair of brake light led bulbs currently on their way to me so i feel comfortable that they will function properly also.

good luck
