About Us

Dorman's engineering heritage goes back over 130 years. The innovation and design-led business philosophy revolves around listening closely to customers and ensuring product development is always focused on their requirements.

Dorman is a leading light in road and rail with extensive product ranges available throughout the UK and in more than 30 countries across the world. Dorman has been at the forefront of LED technology since the 1980's.

LED lighting offers unrivalled safety and economic benefits when compared to filament bulbs and the company's technological leadership has resulted in several industry 'firsts', including ConeLITE, the industry-standard warning lamp for road hazards, and the Dorman Position Light Signal, introduced in 2000 and the first LED signal which controlled train movement fully approved by Network Rail to Railway Group Standards.

The Dorman Product ranges include a complete range of LED signals for all aspects of rail signalling in addition to the portfolio of road products from hazard warning lamps to vehicle activated signs.

Our Products are available through stockists and distributors in the UK and agents throughout the rest of the world. Our 5500sq m production headquarters offers full design, 3D CAD, prototyping, testing, tooling and manufacturing facilities.

As part of Unipart Rail, our use of the renowned Unipart Way of working means that quality is managed throughout every aspect of our business.
