Cadillac ATS Coupe LED Door Sills - Custom Illuminated Plates

Cadillac ATS Coupe LED Door Sills

Cadillac ATS Coupe (2014–2019) LED door sills — illuminated threshold plates made to fit this generation. Choose the design that matches your ATS Coupe's interior trim and get a sharp branded entry accent with every door open.

Installation and Wiring

These LED door sill plates mount on the flat metal threshold using automotive-grade adhesive — bonded to the metal, not the plastic surround. Wiring connects to a door-activated interior circuit for automatic illumination. The connection is typically made at the B-pillar loom or interior fuse box for the cleanest result.

• Adhesive-mounted directly to the door threshold metal
• Door-activated wiring — illuminates when door opens
• No drilling or trim modification required
• Built for daily entry cycles on driver and passenger sides

Available in polished stainless steel, matte PRO finishes, illuminated custom logos, multiple static colors, and FLOW app-controlled RGB lighting for selected designs. Each option is engineered to complement Cadillac's premium interior standard.
