The NARVA W5W car bulb runs on 12 V, draws 5 W and comes as a pack of 2, so both sides can be replaced in one go. Its W5W wedge base is the fitment used for parking lights, licence-plate lights, boot and dashboard lighting in most passenger cars.

The glass wedge base pushes straight into the socket — no twist, no spring clip — so the swap is done by hand without tools. Check the marking on the socket or in your car manual before buying.
