K.W. Muth Company History
K.W. Muth Company was founded in 1947 by Kenneth W. Muth (Ken) in his Grandmothers garage where he devised a paper making machine that prolonged the life of batteries. The company evolved into a wood-based manufacturer of Dental bibs, Barbie Doll houses and basketball backboards, and many other wood-based products. Mr. Muth also sold roof liners, door panels and sun visors for the Nash Rambler in the 1950s. Ken’s son, Michael D. (Mike) Muth became President in 1972 and focused the company as a leading supplier in the automotive segment for cars and trucks.
Under his direction, Mike transformed the K.W. Muth Company in the 70’s into a manufacturer for the automotive industry. The company produced acoustical packing, door and headliner trims and rubber floor mats for GM, Ford and Chrysler. This division was sold in 1992 to Masland Industries, which later was acquired by Lear Corporation.
In 1992, K.W. Muth Company formed a division named Muth Mirror Systems and started developing its patented Signal® Mirror technology. Today, Muth has shipped over 9 million Signal® Mirror units to the OEM and Aftermarket customers. (See website for available cars and trucks.)
Since 1947, the company remains private and family-owned with Kenneth (Ken) W. Muth (3rd generation) acting as Chairman / CEO. Under Ken’s direction, our company remains highly focused and dedicated to innovating affordable safety solutions based on its LED-based Signal and Blind Spot Detection systems for its OEM and Aftermarket customers. As a family-owned business, we pride ourselves on our integrity, high-quality, and safety based products, which our staff has over 80 years of experience at Muth and more than 1.5 times that of Automotive expertise.

I was wondering if you make Signal® Mirrors for a 2009 Buick Lucerne it has heated mirrors now but no signal. What the cost would be? I ordered some Signal® Mirrors for my 1999 Ford F150 2weeks ago they work excellent. The service was great also. Here the next day. I will be glad to here from you soon thanks Tim
