On my 2003 X, I can get the passenger side to accept a high intensity T10 LED but when I put the same known good LED bulb in the driver side puddle position, when activated the driver side gives just one quick little flash and then nothing.
A conventional incandescent on the driver side illuminates just fine as does the pass side LED. So, for now, I'm resigned to a very nice white LED on the passenger side and a yellowish incandescent on the driver side (big sigh).
A minor aberration in the grand scheme of things
