Bulb model number for lights and locations [USDM]

Hi All, I’ve been trying to get a together a list of bulbs and model numbers. I’m a REAL big LED fan, clean and bright as hell has been my thing with my past two cars (Prius and Evo). However looking at the bulb replacement guide on Sylvania’s website I’m slightly confused as to the location and ‘normal’ operation of each light. And it doesn’t help that most of my bulbs are blown own and not working. After some testing with the surviving functional ones I think I’ve got it down, but need a little help and clarification.

Please refer to the pictures as well as the number guide. Down below I’ve compiled and cleaned up the list of bulb part numbers required. Please feel free to add some items to his if I’ve missed them. I also would like to know if I have the operation of the signals correct. Please feel free to correct as I will update the first post.

Front Picture Front:
1. Turn Signal??? [Need Clarification]
Operation: Light comes on when the ‘parking’ [middle selection] is selected on the lights stem. Additionally this light counter blinks with the turn signal when signaling a turn or when hazards are on.
2. Side Marker??? [Need Clarification]
Operation: Light illuminates and stays constantly on when in parking and or full low beam mode [3rd selection on light stem]
3. Low beam
Operation: Light comes on when in full low beam mode [3rd selection on light stem]
4. High Beam
Operation: Light turns on when ‘high beam’ function is selected
5. Turn signals??? [Need Clarification]
Operation: Light blinks counter blinks when a turn is signaled. Illuminates on all three light modes.
From Picture Rear:
1. Rear Side Marker??? [Need Clarification]
2. Rear Turn Signal
Operation???: This turn is amber in color and blinks when a turn function is selected form the light stick
3. Parking Light??? [Need Clarification]
Operation:??? [Need Clarification]
4. Brake/Stop Light
Operation: Brakes are illuminated to their fullest when the brake pedal is stepped on. However when the lights stem selection is at ‘parking’ or ‘low beams’ these lights will be illuminated.
5. Backup/Reverse Lights
Operation: Illuminate white when a car is put into the reverse gear.
6. License Plate Lights
Operation: Lights illuminate when in low beam mode [3rd selection on light stem]
7. Third Brake Light/High Mount Brake Light
Operation: Similar to that of the stop lights. This light is illuminated when the brake pedal is depressed. However unlike the stop lights it is not illuminated by default when in ‘parking lights’ or ‘low beam’ operation.

Industry Common Part Number Cross-Reference. Listed on the left hand side are common bulb sizes/sockets and on the right are compatible reference numbers. For example our clusters use a 2721 sized bulb. However this can be cross-referenced to the standard 74 size. Meaning if you buy a 74 sized bulb it will fit in your cluster.
