The Chevrolet Tahoe parking light utilizes 4157NA, 5702AK, and 2357NA bulb sizes for the exterior lighting system. Data for the specific components covers the period from 1995 through 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Tahoe front parking light specifications list three distinct bulb types across model years: the 7444NA, 4157NA, and 2357NA as ANSI-standard bulbs, alongside the 5702AK as a Sylvania-specific part number.
The 4157NA is the most frequently specified bulb across the listed model years, covering the 2002-2003 and 2005-2007 Tahoe, as well as the late-model 2000 variant.
The 4157NA is a dual-filament wedge bulb in the T25 form factor with natural amber glass, rated at 12V and drawing 27W on its high filament and 7W on its low filament.
The 7444NA, specified for the 2021-2022 Tahoe, shares the same dual-filament construction and natural amber glass as the 4157NA but uses the smaller T20 wedge form factor and carries lower wattage ratings of 21W and 5W.
The 2357NA, specified for the 1995-1999 Tahoe and the early-model 2000 Tahoe, differs from the other listed bulbs in its base type, using a BAY15d bayonet base rather than a wedge base, which makes it physically incompatible with wedge-style sockets.
The 5702AK is a Sylvania part number for a coated variant of the ANSI 3157 bulb, sharing the T25 wedge form factor and 27W/7W ratings of the 4157NA but using an amber coating rather than natural amber glass to achieve its color output.
The 5702AK was specified for the Chevrolet Tahoe in 2001 and 2004, years that otherwise fall within a broader range dominated by the 4157NA, indicating that the two bulbs are not universally interchangeable despite their shared wattage and form factor.
The model year 2000 Tahoe carries two separate front parking light specifications, with the early-model variant requiring the 2357NA bayonet-base bulb and the late-model variant requiring the 4157NA wedge bulb, reflecting a mid-year production change.
All four bulb types listed in the specifications are dual-filament designs, meaning each bulb serves two lighting functions within a single housing, typically combining a brighter turn signal or running light function with a dimmer parking or position light function.
The natural amber glass construction of the 7444NA, 4157NA, and 2357NA produces amber light output through the glass itself, whereas the 5702AK achieves amber output through a surface coating applied to the bulb envelope.
