there are several options 4 dealing with this issue.
1. buy the older style filament bulb housing and install (about 10-12$ each)
then one could REPLACE the filament bulb with a direct led replacement,
or just keep using incandescent bulbs which are widely available.
2. purchase (25$ each) the initial led/upgrade unit (used in 06/07)
it is MUCH BRIGHTER than the current oem and sorta serviceable.
that replacement is covered in this thread in great detail and with lots o'pix...
since the aluminum cast/housing is still the same, either approach will fit perfectly.
