The tailgate light on the trunk door of my 07 mazda cx9 grand touring doesn't work. I think it's burned.
Do I need to change the whole part or i can just change the lights inside? And How to?
Should I get red or white light bulb? For braking lightyou just need to change the light bulb, see SECTION 3 in this link :

if you're talking about the license plate light, you just need to change the light bulb also,
no need to replace the whole part, the clear plastic pops out with a flathead screwdriver,
instructions should be in the manual.

So for brake i can get white?Third center brake light already has red lens so get regular white for maximum brightness,
same for quarter panel rear tail lights, unless you have the LED type, then forget it, for 2013 thru 2015, mazda went cheap and got rid of the LED quarter panel taillights.
Turn signals are amber color,
Only one that should be white is the license plates lights, get low profie white LEDs for the license plates lighting they like nicer than the old fashioned yellowish lights.
So for brake i can get white?
See the arrow. I'm talking about that lightdepends on which brake light you are referring to and what year is your CX-9,
there are 3 total,
qty. 1 in the middle high on top center below rear spoiler
(I just checked, this is a custom LED, not a bulb, you have to buy an OEM replacement.)
qty. 2 on either side by the quarter panels, if your CX-9 year is between 2007-2012,
you can't change the lights in those quarter panel tailights, those are custom LED circuit boards,
you have to buy the Mazda OEM WHOLE assembly, it's not cheap.
While in park and when it's dark and with the engine shut off,
have someone sit in the driver seat and press the brake pedal while you stand in the back
and see which brake light does not light up.
if your CX-9 is 2013+ then the quarter panel lights are just regular inexpensive old fashion bulb that you can change yourself

I would check the fuses first just to rule those out first before buying expensive OEM parts.
I'm going to guess either a 194 or a 7440, as is customary for Mazda. The Sylvania guide offered no help.
