Start an automotive lighting upgrade by deciding what you are replacing, then match the exact product to your vehicle. A familiar model name or a similar-looking lamp is only the beginning: the year range, factory equipment, selected option and package contents all belong in the decision.

1. Choose the part you need

Your project Start here Check before ordering
Replace the main headlight assembly Automotive headlights Exact year range, factory lighting equipment, side or pair, included adapters and installation instructions.
Replace or upgrade the fog lights Automotive fog lights Factory fog-lamp shape, bumper, mounting points, connectors and whether the listing is a complete kit or a separate component.
Replace the main rear lamps Automotive tail lights Body style, original lamp equipment, sensor requirements, selected lens and package quantity.
Replace a bulb, driver or adapter Replacement headlight bulbs or automotive accessories The exact bulb base, assembly, connection or application named by the component.

2. Identify your vehicle and its existing lights

Have the model year, model, trim and factory-light configuration ready. Where a listing distinguishes halogen, HID or factory LED equipment, select the option that matches the vehicle as it is equipped. For a vehicle with previous modifications, inspect the current assembly and connectors rather than relying on the original trim description.

The automotive collections let you start by lighting type or vehicle make. Use the available vehicle filter to narrow the choices, then read the fitment requirements on each result. A model collection can contain products for several generations and configurations.

3. Compare the exact configuration

Once you have a compatible application, compare the features of the selected product and option. A lens colour, daytime-running-light choice, output tier or factory-equipment option can identify a different SKU. Do not assume that features described for one version carry over to another version in the same family.

Keep headlight and tail-light applications separate. Their supported year ranges and equipment requirements may differ even when they are being purchased for the same vehicle. If you choose a combination package, read the application for the complete package.

4. Read the included-parts list

Confirm whether the price covers one lamp, a pair, a complete vehicle kit or a supporting part. Check the selected SKU for bulbs, modules, adapters, harnesses and mounting hardware. A photograph of an installed setup does not replace the package list.

Review the installation guide before placing the order. Note any required wiring connection, transferred original component, equipment setting or additional part. Choose accessories only where their compatibility with the exact lamp or kit is established.

5. Keep the product role clear

Headlights, fog lights, main tail lights, third brake lights and auxiliary lights serve different positions in a lighting setup. If you are building a separate auxiliary-light system, use the off-road lighting collections and their vehicle-kit information. Match the product’s stated application and installation requirements to the job you intend it to do.

Automotive lighting questions

Is a year, make and model match enough?

It narrows the search, but the listing may also specify factory lighting, trim, body style, market or equipment restrictions. Read those requirements before selecting the final option.

Does every headlight listing include both sides?

No single quantity rule applies to the whole collection. Check whether the selected listing specifies a pair, one lamp or a particular side, and review the included components.

Can I choose only by the product photo?

Use the photo to understand the product, then confirm the exact SKU, fitment and package contents. Shared family photographs or installed examples may show more than the selected purchase includes.

What should I do when the finder has no verified result?

Use Show all products to browse the collection, or gather your vehicle year, model and photos of the existing lamps and connections for help identifying a suitable option. A missing verified result is not a fitment confirmation for a similar-looking product.

Should I replace a bulb or the entire assembly?

Start with the component you intend to replace and the construction of your existing light. Compare replacement-bulb listings with complete assemblies and supporting parts; use the product’s application and installation information to choose the right purchase.

Three examples from the BTS catalogue

Same truck and model year, different original headlights

For a 2022–2026 Toyota Tundra, the FORM FL0101 headlight pair is the package for factory reflector headlights, while the FORM FL0111 pair is for factory projector headlights. Inspect the original lamp design rather than choosing from a trim badge alone. These Tundra requirements do not establish which package fits a Sequoia.

A headlight listing can be one lamp or a complete pair

The Morimoto LF271 Sealed7 2.0 listing is one lamp. Its documented 2007–2017 Wrangler JK application also needs separate LF272 anti-flicker adapters. The LF515 Super7 JK listing is a left/right pair with its supplied external drivers and anti-flicker modules. Its application is 2007–2018 left-hand-drive JK with original halogen headlights. Compare the exact product’s quantity, equipment and installation requirements instead of assuming every round Jeep headlight is the same package.

Lens choice and signal operation are separate decisions

The 2010–2024 4Runner FORM tail-light pair offers red or smoked lenses and static or sequential turn signals. Its startup sequence and sequential operation can be disabled at the lamps. Choose the appearance you want, then review that listing’s configuration instructions; those settings are not a promise about other tail-light families.
