First generation (2017-present) · Small premium crossover / B/C-segment SUV
Interior LED bulbs in the Volvo XC40 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 moderately CANbus-sensitive.
Three products we would look at first in this category. Fit for your Volvo still comes first: check the compatibility list on the listing against your exact model and year, and read the model guide above.
