Choosing replacement truck tail lights
Read more: match the light to the mounting opening
For an existing oval opening, begin with 2×6 oval tail lights. For a round opening, compare 4-inch round tail lights. Measure the opening and available rear clearance, then check the selected lamp’s dimensions and mounting information.
Flange-mount products and lights intended for separate mounting parts may require different installation hardware. Keep the current light’s part number and photos of the front, rear and connector available when comparing replacements.
Read more: choose the function before the lens style
These collections include stop/turn/tail, turn-signal and back-up models. Select the function your installation needs before comparing lens finishes, LED patterns or additional lighting effects. A shared size does not make two lamps functionally interchangeable.
For a longer lighting format, browse signal light bars. Check the stated length and lighting function, and distinguish a complete light from an auxiliary strip, housing or bracket. Lens appearance alone does not establish the emitted light colour.
Read more: plan the complete installation
Compare the electrical requirements, connector, wiring instructions, mounting parts and package quantity for the exact product. Check which accessories are included and which are sold separately. Heated lenses and additional lighting modes are model-specific features.
For the rest of your lighting project, explore tail lights and marker lights. If you are replacing a serviceable bulb rather than a complete lamp, browse signal and brake bulbs. Confirm the installed lamp’s requirements before selecting parts.
Before you order
Truck tail light FAQs
How do I choose between oval, round and bar-style tail lights?
Start with the existing opening or mounting bracket. Compare the product’s full dimensions, depth and mounting method with the available space. A 2×6 oval or 4-inch round category label is a starting point, not a complete fitment specification.
What is the difference between stop/turn/tail and back-up lights?
The listed function tells you which lighting duties the product supports. A stop/turn/tail light and a back-up light are different options even when they share a shape. Match the required function, emitted colour and wiring arrangement to the exact product.
Does a clear lens mean the light shines white?
No. These collections include red LED/clear-lens and amber LED/clear-lens products, as well as white back-up lights. Read both the LED colour and lens colour in the selected listing.
Will my existing plug work with a replacement LED light?
Check the connector or wire leads, voltage and wiring diagram for the exact light. Similar-looking lamps may have different connection requirements. Confirm whether a pigtail or adapter is supplied or needs to be ordered separately.
Are grommets, bezels and brackets included?
Package contents vary. A light-only listing, a flange-mount light and a complete kit can include different parts. Check for the required grommet, bezel, mounting hardware and wiring accessories before placing the order.
Are heated lenses available on every tail light?
No. Heated-lens models appear in the oval and round collections, but the feature is specific to the selected product. Check the exact listing rather than assuming every light in that size has a heated lens.
Can an auxiliary or decorative light replace a required signal light?
Choose a product explicitly listed for the lighting function you need. The signal-bar collection also includes auxiliary strips, housings and brackets, so the category name alone does not establish a lamp’s function. Review the product’s stated intended use and specifications.
Are tail lights sold individually or as a pair?
Check the package quantity on the exact product. Do not assume that a photo, size group or kit name means two lights are included. Count the lights and installation parts needed for your project before ordering.
Need help matching a tail light?
Send the current light’s part number, dimensions and photos of its mounting and connector so our team can help narrow down the options.
