A 38-Year Legacy of Warning Light Manufacturing at LIYI

Since 1987, LIYI has been dedicated to the special vehicle warning light industry. Over nearly four decades, we have weathered industry shifts, mastered new technologies, and stayed true to a simple belief: a warning light must work when it matters most.

From Incandescent to LED

• Incandescent era — we built our foundations understanding durable mechanical construction and reliable wiring.
• Halogen transition — we learned to manage heat, reflectance, and power draw in signal lighting.
• LED revolution — we retrained, redesigned, and re-engineered our entire catalog around efficient, long-life LEDs.
• Smart and connected future — we keep evolving, integrating enhanced drivers and standardized communication for modern fleets.

The Value of Experience

Three and a half decades isn't just a number. It means we've seen what fails in the field and fixed it before our competitors encountered it. Our production line reflects those hard-won lessons in every weld, every seal, and every optical consideration.

Our Honest Commitment

We don't chase fads. We build on experience, refine with modern technology, and stay focused on what has always mattered: giving professionals a warning light they can trust to perform when lives depend on it.
