Additional Notes

The Toyota Sequoia daytime running light specifications for 2008-2018 reference two bulb types: the 4157NA and the 5702AK. Both share the same T25 wedge base form factor and identical electrical ratings of 12V with a dual-filament output of 27W on the high filament and 7W on the low filament.
The 4157NA is an ANSI-standardized bulb recognized across the United States and Canada. Its amber color is produced through natural amber glass, meaning the tint is built into the glass envelope itself rather than applied as a surface treatment.
The 5702AK is a Sylvania-specific part number representing a coated variant of the ANSI 3157 bulb. Its amber appearance comes from a coating applied over the bulb surface rather than from the glass composition, which distinguishes it from the 4157NA despite their shared electrical and physical characteristics.
Because the 5702AK is a manufacturer-specific designation, it is not an ANSI-standardized number. Sourcing an equivalent from another brand requires cross-referencing to the underlying 3157 specification with an amber coating, rather than searching by the Sylvania part number alone.
The 4157NA is the more frequently specified bulb across the Toyota Sequoia daytime running light data, covering model years 2008-2010, 2012-2014, and 2016-2017. The 5702AK is specified for 2011, 2015, and 2018.
Although the 4157NA and 5702AK share the same T25 wedge base and 12V/27W/7W ratings, the difference in amber production method means they are not unconditionally interchangeable in all applications. Some vehicle lighting assemblies are calibrated for a specific light transmission quality, and substituting a coated bulb for a natural amber glass bulb, or vice versa, may affect the output characteristics at the lens.
The dual-filament design of both bulb types means each bulb contains two separate tungsten filaments operating independently. In daytime running light applications, typically only one filament is active during normal DRL operation, with the second filament serving a separate function such as turn signal or parking light duty within the same housing.
