I don't know if the '07's use different bulbs, but I can tell you what I did on my '03 when I put in LED lights (learned it on here). The dome light on the '03 uses a 194 bulb....a small wedge base bulb. That one went in and worked with no problems. For my map lights on the overhead console, it uses festoon bulbs....the long glass tubes. With just the LED bulbs in there, they would strobe, and when off, they would still be faintly lit. I just put a small resistor across the bulb, from one end to the other, and it fixed the problem. :rck:
