Toyota RAV4 brake bulb specifications include 7443 and 1157 sizes for standard brake applications, along with 7440 and 921 sizes for center high mount stop light functions. The replacement chart covers vehicle production years spanning 1996 through 2018 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7443 is the most widely used brake bulb type across the Toyota RAV4 specifications. It is a dual-filament T20 wedge bulb rated at 12V with a 21W high filament and a 5W low filament, conforming to ANSI standards for the US and Canadian markets.
The dual-filament design of the 7443 allows it to serve both brake and tail light functions within a single bulb, which is a common arrangement in combined stop and tail light assemblies.
The 1157 also carries a dual-filament configuration rated at 12V, 21W/5W, but uses a BAY15d bayonet base rather than a wedge base. This base type difference makes the 1157 and 7443 physically incompatible with each other despite sharing the same wattage ratings.
The 7440 is a single-filament T20 wedge bulb rated at 12V, 21W. Although it shares the T20 wedge form factor with the 7443, its single-filament construction means it is not interchangeable with the 7443 in positions that require dual-filament operation.
The 921 is a T15 wedge bulb rated at 12V, 16W with a single filament. Its smaller T15 form factor distinguishes it from the T20-based 7440 and 7443, making cross-substitution between these types unsuitable.
The Toyota RAV4 (1996-1997) used the 1157 bulb for the outer brake position, while the 1998 model year saw a mid-cycle transition to the 7443, with production built to 09/1997 retaining the 1157 and those built from 09/1997 onward using the 7443.
For the 2016-2018 RAV4, the brake bulb specification of 7443 carries a conditional note indicating it applies to vehicles equipped with Halogen Capsule Headlamps, reflecting a trim-level dependency in the fitment.
The center high mount stop light on the 1996-1997 RAV4 used the 921 bulb, while the 1998-2005 model years transitioned to the 7440 for that position.
All four bulb types listed in the specifications, the 7443, 1157, 7440, and 921, conform to ANSI standards applicable to the US and Canadian markets and operate on a 12V electrical system.
The 1996 outer brake specification notes production from 11/1995, indicating the 1157 fitment applies to vehicles assembled from that date within the 1996 model year run.
