Sorry for butting in, Dale, but as the only one of us here with an English degree (I imagine), maybe I ought to say that you may actually be referring to the brake lights on the extreme right hand side of the car. These form a pattern sort of like this:
Toyota seems to call the light bulb that lights up when you press on the brake pedal the "tail light." This is correct, as far as it goes, but doesn't do a very good job of telling you that the "tail light" bulb has two parts (filaments) in it: one part is the regular tail light, which stays on all the time when the lights are on, and the other part is the light that comes on when you press on the brake pedal. Toyota calls this function the "stop light."
The confusion comes between the index, which calls this the "stop and tail lights," and the diagram on page 308, which only identifies the bulb as the "tail light." I guess this is correct as far as it goes, but it would have been a lot clearer if the index had called it something like the "combined stop and tail light bulb." I personally like the term "brake light" better than "stop light," since we've all been saying "brake light" for as long as we can remember, and to us all the term "stop light" is that red light hanging way up high in the middle of the street.
The name "stop light" is, I believe, the term that the guys here use to refer to the bar of lights in the middle of the car, the little lights in the "spoiler," which is between the two parts of the rear window, and which is just about six inches above the chrome Toyota logo in the exact middle of the car.
I'm sorry for my first posting which just said that the diagram on page 308 is correct. I only meant that the light bulb in question is actually shown there, but I should have been a lot clearer. By the way, Toyota just reproduced the 2005 year's page 308 and put it into the 2006 year's owner's manual as page 423.
So, we all hope that, just as you originally said "One of the six stop lights on the right rear of my 2005 is burned out," and not that the bar of lights, which we all call the stop lights, is not working.
Here's what to do:
1. Open up the hatchback so that you can get to the little door shown on page 308 of the manual.
2. Get someone to put the car into "Ignition On" mode or just start the car, but BE CERTAIN TO PUT IT INTO PARK before walking behind it.
3. Be sure that the light switch inside the car is turned OFF. Have someone press on the brake pedal.
4. Determine if some of the brake lights on the right-hand side are really not working. (You can tell this by comparing them with the pattern formed by the brake lights on the left-hand side.)
5. I believe that this is an "all or nothing" function, so that if you have any brake lights on the right-hand side, the "tail light," to use Toyota's term, is good.
6. Before you do the following step, make sure that the car is turned off and that nobody is pressing on the brake pedal.
7. If you don't have any brake lights on the right-hand side, open up the little plastic door and take out the bottom bulb. If you look on page 305, there is a DASH instead of a number for the bulb type for the "tail light." I don't know what this means, unless it means that you can't expect to find the bulb at an auto parts store and must buy it at your Toyota dealer.
8. So maybe it would be best if you determine that the right-hand side brake lights are not working to go to the Toyota dealer and buy the bulb there first.
I'm sorry that this posting is so long, Dale, but I hope that it helps understand Toyota's diagram on page 308 plus their wording in the index and on pages 304 and 305.
