A BA15s parking-light bulb for 12 V systems, supplied in pairs so both sides are replaced at once.
The NARVA R5W is a 12 V, 5 W spherical bulb with a BA15s base, used for parking and position lights, licence-plate lighting and interior lamps. Each blister holds 2 bulbs (item no. 455770).
BA15s base fits standard parking-light holders
The single-contact bayonet fitting twists and locks into the holder, keeping the bulb seated despite road vibration. R5W is an international designation, so compatibility is checked against the bulb type listed in the vehicle manual.
Two bulbs per pack for both sides
Parking lights work in pairs and usually fail within a short span of each other. The pack covers left and right in one go, or leaves a spare in the glovebox for the road.
