Second generation (P21, 2019-present) · Supermini / small hatchback
Interior LED bulbs in the Peugeot 208 are a size-code exercise first and a CANbus exercise second. Get the bulb code right (194, T10, festoon 31 or 36 or 42 mm, W5W or C5W), then decide whether CANbus-decoded bulbs are worth the small extra outlay given that this car is mildly CANbus-sensitive.
Third generation (P54, 2024-present) · Family SUV coupe / C-segment fastback SUV
Interior LED upgrades in the Peugeot 3008 are one of the quicker cabin jobs. Nearly every fitting uses a small wedge (194 or T10) or a festoon bulb between 31 and 42 mm long; the code is printed on the metal cap of the existing bulb, and every kit worth buying lists its bulb code the same way.
Three products we would look at first in this category. Fit for your Peugeot still comes first: check the compatibility list on the listing against your exact model and year, and read the model guide above.
