Turn signal works off a third bulb, that I believe is the reverse light. All signal and running lights work, just not the brake lights(#1 and #3 bulbs respectively, and that is with the new bulbs in as well. I have been reading up on the Toyota forums that this is sometimes caused by bent pin connections where the bulb socket screws into the integrated housing. I just need to pull them again when the car gets home and I'm home to see if this is the cause, mind you it would be helpfull to have a pedal pusherer!
