Product Overview
A branch strike, loader debris, cracked lens, water intrusion, or an open lamp circuit can leave the left front of a tractor dark. This assembly restores the lamp housing and lens when the tractor-side wiring, fuse, switch, and ground remain serviceable.
This is the left headlight assembly, not a right-hand lamp and not necessarily a bulb-only service part. Hood and grille revisions can change mounting even within the same base model.
Confirm operator-left position, plug, mounting tabs, lamp shape, model suffix, and original number. Compare the removed assembly to the product photos before ordering.

Frequently Asked Questions
Q: Is this only the bulb? A: No. It is the left headlight assembly shown; verify whether a bulb is included.
Q: How do I identify the left side? A: Left and right are normally determined from the operator seat facing forward.
Q: Will it fit every M5040? A: No. Model suffix, hood revision, connector, tabs, and part number must match.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
