RIGHT TAIL LIGHT FOR NEW HOLLAND AND CASE IH: 5186340

Right Rear Taillight for New Holland and CASE IH Tractors, Part No. 5186340

This right rear taillight corresponds to part number 5186340 and is used on several New Holland and CASE IH listed in the applications section of this product sheet. It is a rear lighting component designed to be mounted on the right side of the machine. To ensure a proper replacement, verifying the mounting side and part number is the most reliable method.

Location and Function on the Tractor

Mounted on the rear right side, this light contributes to the machine’s visibility and signaling both while moving and during operation. On a tractor, a damaged light can hinder other road users’ ability to see the machine or make the rear less visible in low-light conditions.

Replacement is generally recommended when the housing is cracked, broken, or tarnished, or when it no longer functions properly. With this type of part, it is important not to confuse the right side with the left side, even if they look similar at first glance.

Part Numbers to Compare and Known Applications

This part number is first identified by its number 5186340. A match with COBO 04311000 is also indicated, which can help match the part to an existing assembly. These part numbers serve as a basis for identification before ordering, in addition to the exact model of your tractor.

The listed applications include, in particular, New Holland tractors from the T4000 and TN series, with models such as the T4020, T4030, T4040, T4050, TN55, TN65, TN70, and TN75, as well as various A, DA, SA, F, N, S, V, or Deluxe variants depending on the model. Installations on several CASE IH JX tractors are also documented in the compatibility information associated with this part number.

Helpful tips for choosing the right taillight

To select this right rear taillight, start by checking three simple points:

• the part number on the old part or in your documentation;
• the right-side mounting;
• the exact tractor model, including its full designation if a variant is specified.

This check is especially useful for series with several similar versions, such as those with suffixes like Deluxe, F, N, V, A, DA, or SA. An incomplete designation may lead you to choose a light intended for a different configuration within the same tractor family.

When to Replace This Part

Replacing a right rear taillight is recommended after an impact, a broken lens cover, visible water ingress, or a lighting malfunction detected on the right rear side. A new part ensures a clean and clearly identifiable assembly, provided you confirm the correct part number beforehand.

If you are looking for this part for a New Holland T4000, TN, or CASE IH JX tractor listed in the applications, compare your part number and the exact model name before confirming your selection.

This right rear taillight is used to ensure visibility and provide signaling at the rear of the tractor, on the right side. On this type of machine, it is one of the components that should be checked regularly after an impact, a cracked lens, or a noticeable decrease in visibility.

How do I verify that part number 5186340 matches my setup?

The first step is to compare part number 5186340 with the part you removed or with your maintenance documentation. You can also cross-reference it with COBO part number 04311000, then confirm the right side and the exact tractor model listed in the application list.

Is this right rear taillight compatible with a New Holland T4030 or a TN75DA?

What is the difference between a right rear light and a left rear light?
