I have a 2015 Wliiys 4dr 6spd manual. Anyone ever seen the shift light as described in the owners manual ( upshift and downshift ) is it not working or not used. Never saw saw it illuminate after 2 months of ownership.

I have an auto so mine won't have this but you won't miss it. It's just a brainless holdover from the 90s that supposedly will help with fuel economy but never does. The best thing to do is to know the vehicle and develop a sense for when shifts are needed. You can probably do this already.

A manual JK doesn't have a shift light. That would be for an auto when it's in "manual" mode. The "shift" light illuminates when a manual shift is required on an auto trans. This further explains it on an auto:
Electronic Range Select (ERS) Operation

The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.

You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically, shifting
between all available gears. Tapping the shift lever to
the left (-) will downshift the transmission, activate ERS
mode, display the current gear in the instrument cluster,
and maintain that gear as the top available gear. Once in
ERS mode, tapping the shift lever to the left (-) or right (+)
will change the top available gear.

To exit ERS mode, simply press and hold the shift lever to
the right (+) until “D” is once again displayed in the shift
lever position indicator in the instrument cluster.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), tap the shift lever to the
left (-) repeatedly as the vehicle slows. The transmission
will shift to the range from which the vehicle can best be
slowed down.

There's an Eco light. I shut mine off in personal settings in my evic. It wasn't a light per se but Eco written out below the info center where the compass and temp is written out. Now that mine is turned off the radio station I'm on is written there.

I shut mine off by installing 5:38 gears, you dont have to worry about it coming on when you are turning 3 grand.
