The Argo Xplorer front turn signal requires a 12496 bulb size while the rear turn signal uses a P21W bulb size. The replacement chart covers vehicle production years spanning 2018 to 2019 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 Argo Xplorer (2018-2019) uses two distinct bulb types across its turn signal positions, with the front and rear positions requiring different bulbs that are not interchangeable with each other.
The front turn signal on the Argo Xplorer (2018-2019) takes the 12496, a halogen bulb operating at 12V and designated under Philips and Osram part numbering for specialty applications.
The 12496 is a manufacturer-specific part number rather than a universal industry standard, meaning it is referenced through Philips and Osram catalogues rather than a broader regulatory classification.
The rear turn signal position uses the P21W bulb for both the 2018 and 2019 model years, a single-filament signalling bulb rated at 12V and 21W.
The P21W is defined under ECE (Economic Commission for Europe) standards and sees use across international markets, giving it broad availability relative to manufacturer-specific designations.
The P21W uses a BA15s bayonet base, which is a single-contact bayonet fitting. This base type is not compatible with dual-contact bayonet sockets, making socket type a relevant factor when sourcing a replacement.
Both the 12496 and the P21W operate on a 12V electrical system, consistent with the standard automotive voltage found in the Xplorer.
The front and rear turn signal bulbs differ in their classification systems, with the front using a brand-assigned part number and the rear using an ECE-standardized designation, which affects how replacements are sourced across different markets.
