Yesterday I had to replace the passenger side stop/taillight bulb in our '08 Sienna, and so I go to the owner's manual to look for a bulb application chart. I look through the DIY section - plenty of info on how to replace bulbs, but no bulb chart. Also nothing in the specifications section.
I've owned everything from a '64 Pontiac Grand Prix to a '78 Audi Fox, and I've never seen an owner's manual that didn't have a bulb chart. Weird.
I assumed it would be an 1157, or a 3157 like my F-150 uses. Wrong. It takes a 7443, a dual filament bayonet-type bulb, which I'd never heard of before.
It took me awhile to get the lamp off, as I didn't realize there were pins holding it in on the outside of the body. Stupid me, I assumed it slid in from the back, like the ones on the Previas. So I pried and pried on it, hoping I wasn't going to break it. Then, the pins popped out, and the lamp came off.

You learn something every day.
