Scion FR-S headlight bulbs utilize D4S and 9005 sizes for high beam applications, while low beam configurations employ D4S and H11 bulb sizes. The replacement chart covers 2013 through 2016 model production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Scion FR-S uses three distinct bulb types across its headlight system: D4S for HID configurations, 9005 for halogen high beams, and H11 for halogen low beams.
The D4S is a mercury-free xenon discharge bulb operating at 42V and 35W, built to ECE standards with a P32d-5 base and designed specifically for projector-type housings.
The 9005 is a single-filament halogen bulb built to ANSI standards, carrying a P20d base and rated at 12V and 65W, making it the highest-wattage bulb among the three types used in the FR-S headlight system.
The H11 is a single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W, and holds both ECE certification and US approval.
For the 2015-2016 Scion FR-S, the headlight bulb requirements depend on which headlamp system is installed. Vehicles fitted with HID headlamps use D4S bulbs for both high and low beams, while those fitted with halogen capsule headlamps use a 9005 for the high beam and an H11 for the low beam.
The base types across these three bulbs are not interchangeable. The D4S uses a P32d-5 base, the 9005 uses a P20d base, and the H11 uses a PGJ19-2 base, meaning each bulb fits only its corresponding socket.
For the 2013-2014 FR-S, the high beam position takes a 9005 and the low beam position takes an H11, with no HID variant listed for those years.
The voltage difference between the D4S at 42V and the halogen types at 12V reflects the fundamentally different operating principles of HID discharge technology versus standard halogen filament technology, and the two systems are not electrically compatible.
