GMC LED Door Sills

Begin with the closest model or generation collection, then confirm the exact vehicle year against the selected product. Doorway length, threshold contour, available mounting surface, door clearance, set configuration, and cable exit can differ even when two vehicles share the GMC badge. Use the listing photographs and dimensions as comparison points, not as a substitute for checking the car. If your exact model is not listed, send the model year, clear threshold photos, and available measurements for review. A custom set can be assessed only after the mounting area and required plate shape are understood.

Classic Stainless and Matte PRO are different product families. Matte PRO finish options include painted or powder-coated finishes. Check the finish and available options in the selected product listing before ordering.

Available LED colors depend on the selected product and configuration, so confirm the choices shown on the product page before ordering. Personalized threshold plates may use reviewed custom text or submitted artwork when the sill design supports it. A production proof should confirm wording, scale, orientation, and lighting color before manufacturing begins. Not every color, logo style, or custom layout is available for every plate. Personalization changes the visual result, but it does not determine compatibility: model, generation, threshold geometry, and mounting space must be confirmed first.

Reliable Hardwired Installation uses vehicle power, so these illuminated door sill plates do not require batteries or charging. Dry-fit the plate on a suitable outer painted metal threshold and confirm door, seal, and cable clearance before bonding it with automotive adhesive tape. The electrical connection is wired: red is positive, black is negative, and a door-open signal is recommended so the light follows entry. Plastic trim should not be assumed to be a suitable mounting surface for every GMC. If the mounting area or wiring route is uncertain, an individual review and professional installation by an automotive electrician may be appropriate.
