My 02 lights had original white bulbs and the housing was also white, so maybe the yellow was an option or only on later years - yellow LEDs are available.
And I only got into my
instrument cluster when I discovered the gauge lights are on FULL time, even with the
headlight switch OFF and do NOT dim. The mileage and heater control dimming follows a different path and continues to operate and dim properly.
On inspection I think the classic
FEM failure occurred causing the instrument lights and shifter light to become non-operational. Some previous owner "hot-wired" my
instrument cluster to provide full time power to the instrument bulbs. Rather than deal with the
FEM issue just now, I'm installing 60,000 hour LEDs and they can just burn the whole time the car is running -- which is basically how my modern cars (e.g. Tundra) work... If I decide to fix the
FEM later on there is no downside to having the LEDs. I am using "dimmable" LEDs to that end.
The
instrument cluster removal is not that bad if you have some mechanical skills and follow the
Workshop Manual.
The big problem is that LEDs are polarity sensitive (unlike incandescent bulbs) so I had to sort out where the "negative" side is for
every bulb location in the cluster (ugh!) which I will share once I prove the LED conversion is completely successful and I haven't "screwed the pooch". I will post the whole evolution in a new thread if things go well.
