The Argo Avenger 8x8 uses P21W bulbs for both front and rear turn signal applications, with this size remaining consistent across the vehicle's design. The replacement chart covers 2017 to 2018 model years and documents the bulb specifications for these signal light positions.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The P21W is the sole bulb type listed across all turn signal positions in the Argo Avenger 8x8 specifications, appearing in both the front and rear turn signal applications for the 2017-2018 model years.
The P21W operates at 12 volts and draws 21 watts, placing it within the standard power range for single-filament automotive signalling bulbs.
The P21W uses a BA15s bayonet base, which is a single-contact bayonet fitting with a 15mm collar. The "s" designation indicates a single contact point at the base, distinguishing it from the dual-contact BA15d variant.
As a single-filament bulb, the P21W is dedicated to one function per socket, which is consistent with its use in turn signal applications where a separate circuit handles each lighting task.
The P21W is governed by ECE (Economic Commission for Europe) standards, a regulatory framework recognized across Europe and numerous other markets worldwide.
All entries in the Argo Avenger 8x8 turn signal specifications carry a notation of "European Model," indicating that this fitment data applies specifically to the European-market variant of the vehicle.
