The automotive ambiance lighting market is expected to grow from USD 4.34 billion in 2025 to USD 4.79 billion in 2026 and reach USD 7.84 billion by 2031 at a 10.34% CAGR, according to Mordor Intelligence. Falling LED prices, improved thermal management and AI-driven personalization platforms have shifted ambient lighting from a luxury option to a mainstream feature across compact cars, electric vehicles and premium SUVs. Passenger vehicles held 59.58% of 2025 revenue, and Asia-Pacific leads demand on the back of China's electric-vehicle boom.

By application, footwell lighting captured 33.45% of the market in 2025, while center-console lighting accelerates fastest at a 16.21% CAGR through 2031. OEM installations still account for 78.15% of revenue, but the aftermarket is the fastest-growing sales channel at a 13.62% CAGR as buyers retrofit existing cabins. RINA TECHNOLOGY's multi-color LED ambient strips and smart controllers serve both OEM programs and this fast-growing retrofit segment.
