Tail light/brake light questions Does anyone know offhand from left to right, starting on the left side bulbs, what type of bulbs are used? I apparently put the wrong type in last time, and now have 1156s, 1157s, 2057s, and now have no idea whats going on. I have a 94 TA, but I think the newer ones are the same (I could be wrong).

I think you misread his question - he has a 1994 T/A. They didn't use the wedge bulbs (3157, etc.) back then, they used the double contact indexed bayonet bulbs.
It would be pretty difficult to mistakenly use an 1156 in place of an 1157 because the 1156 is a single contact bulb but the 1157 is double contact. In other words, the 1156 is for use in single function lights such as amber turn signals. The 1157 is for dual function lights such as taillights with a dim filament for parking/running lights and a bright filament for brake lights.
The only real difference between the 1157, 2057, and 2357 is the brightness of the filaments. All three will fit the sockets and work the same. The 1157 has 3 candlepower (CP) on the dim filament and 32 CP on the bright filament. The 2057 has only 2 CP on the dim filament with 32 CP on the bright. And the 2357 has 3 CP on the dim filament and 40 CP on the bright. So, if you want really bright brake lights then get 2357 bulbs.
The side marker lights, license lights and the outboard tail lights use 194 wedge bulbs. The two inboard tail lights on each side use 2057 bulbs because they are the ones that are both running lights and brake/turn signal. The backup lights use 1141 (21 CP) or 1156 (32 CP) single contact bayonet bulbs.
If you decide to upgrade to brighter tail lights with the 1157 or 2357 bulbs then the 194s in the outboard positions will look dim at only 2 CP so you should upgrade them to the 168 bulb which is the same design but puts out 3 CP to match the others.
