Welcome to Caerbont Automotive Instruments Ltd

Caerbont Automotive Instruments Ltd (CAI) is an independent company in South Wales engaged in the design and manufacture of discrete car instruments, instrument clusters, senders, electronic control and interface modules and wiring harnesses for the specialist automotive and industrial markets.

CAI has its roots in the Smiths Motor Accessories business, a pioneer in the development of the UK Automotive Industry. In 1984 ownership moved to the Lucas Group and then to VDO before becoming an independent company following a management buyout in 1993.

CAI was the subject of a second management buyout in 2011 and has branched out into new markets with new products , including Motorcycle and Marine.
