LEFT TAIL LIGHT FOR NEW HOLLAND AND CASE IH 5186339

Left taillight for New Holland and IH Case tractors

The left taillight corresponding to part number 5186339 is designed to replace the rear lighting on several New Holland and IHCase tractors. This part is selected primarily based on its mounting side, part number, and machine application. It is compatible with various tractor models in the T4000, TN, and JX series, as listed.

What is a left rear taillight?

A left rear light is mounted on the rear of the tractor, on the left side relative to the direction of travel. It helps signal the machine’s presence and replaces a light that is damaged, cracked, or has become difficult to read. When replacing a light, it is essential to distinguish between the left and right sides, as the two sides are not interchangeable if their shape or mounting location differs.

For this part number, the best way to identify the correct one is to match the left side designation, the comparison number 5186339, and the exact model of the tractor in question.

Applications identified on compatible tractors

This part is compatible with several tractors from the following brands: New Holland, Case, and CASE IH. Without listing them all here, the following applications are notably included:

• New Holland T4000 series: T4020, T4030, T4040, T4050
• New Holland TN, TNA, TNDA, and TNSA series: TN55, TN60A, TN70DA, TN75SA, TN85A, TN95A
• Case CASE IH ’s JX series: JX 1060, JX 1070, JX 1075, JX 1085, JX 1095, as well as variants such as the JX1060C or JX1095V

These applications cover standard tractors and certain production variants. If your machine has a model suffix, you must include this complete designation when identifying it.

Useful guidelines for selecting the correct part number

The first criterion is the part number 5186339 for comparison. If this part number appears on your old part, in your maintenance documentation, or in your replacement part list, it is a good starting point. The second criterion is the exact tractor model. A single model name may encompass several versions, with or without a suffix, which must not be confused.

If you’re replacing only the left side, don’t assume that the right-side light is identical. On rear lighting assemblies, the external shape, orientation, or mounting may differ from one side to the other.

When should you consider replacing it?

A left rear light is typically replaced after it breaks, cracks, loses visibility, or becomes damaged due to tractor use. On a work machine, a rear light in good condition helps maintain clear signaling during movement and maneuvers.

Before finalizing your selection, simply compare the installation side, part number 5186339, and the full model designation of your tractor with the listed applications.

FAQ — Frequently Asked Questions

What is the purpose of this left rear light on the tractor?

This left rear light is used to indicate the tractor’s presence and position at the rear, on the left side. It is part of the rear lighting assembly and is selected first based on the side of installation, then based on the comparison part number 5186339 and the exact model of the machine.

How do I determine the left side for part number 5186339?
