For the 2010 Ford Transit Connect, the low-beam and high-beam headlights both use an H13 bulb. This fitment data does not identify a separate bulb size for different headlight types, so verify the existing bulb and housing before ordering.
The fog lights use an H11 LED bulb. Front turn signal and parking light fitments include 3457A, while the front turn signal data also lists 194NA; check the lamp position and socket before replacement.
Other useful exterior fitments include 7440 reverse lights, 7443R brake and tail lights, and 7440A rear turn signals. The license plate, front side marker, dome, and trunk lights use 2825 bulbs. The map light uses 6411. Confirm the bulb number against the original part, particularly where more than one front signal size is listed.
