I don't know what light bulb to put in the gear shift

There's should be a shift interlock that prevents it from being put into gear unless the brakes are on; check if the fuse it good for the brake lights; it seems to somehow be tied in with the parking lights, which may be feeding into the brake light circuit.

there is a bulb underneath the shifter panel-pull up the plastic around the shifter and look for it underneath the shifter- it should be a 168-or 194 bulb- cheers Denny

run the fault codes to find the problem sensor
could be TCM, TR sensor or VSS sensor

Check your fuses or the bulb may simply be blown and you will need to remove the faceplate and replace them easy fix.

all you have to do is pop the little square piece around the gear shift lever up and there is a wire with a tiny bulb on it. It is a pain in the butt to get all the pieces back in place and put the square piece back down. i have had to replace mine like every 6 months. be careful not to use too much force because you can break the clips that secure it in place and that will look worse than your bulb not working

YOU NEED TO REPLACE THE SMALL BULBS IN THE DASH AND REPLACE BULB IN THE GEAR SHIFT INDICATOR..

It may be the fuse. Check and replace if necessary. Or the wiring may be grounding somewhere when the bulb is in place. Look for cracks/cuts in the wiring.

If the shift console is on floor then look for bolts holding it down.  Take out bolts and then you can maneuver console so you can see where light is plugged in and get the right light to replace it.  It will probably be a small light which tend to cost a bit more, but at least you'll have the light back.

May Have Blown A Fuse Due To Installing The wrong Bulb .check the brake lights If they dont work May Have Blown A Fuse And Disabled The Shift Interlock At The Shifter Try To Put The Car In Nutral With The Key Off Then Start The Car And See If The Car Goes In Gear

There is a module that controls the lights you listed, it changes the brightness when the headlights are on or off, it may be your problem.
