                                 Trading Update

Dialight plc, the UK based leader in applied LED technology, is today giving a
trading update ahead of its results for the year ended 31 December 2007.

Overall the Board expects that the results for the year ended 31 December 2007
will be in line with market expectations.

Dialight consists of two business segments:

  • Signals/Illumination which includes Traffic and Rail Signals, Obstruction
    Lights and the new Solid State Lighting products
  • Components comprising LED indication products and electromagnetic
    disconnects

The Signals/Lighting business has had a further year of good sales growth with
second half demand helped by the first orders for the white LED Obstruction
light and the Safesite hazardous light product lines. Demand for Components
products stabilised after a slow first quarter and sales achieved for the full
year of 2007 were similar to those of the 2006 year.

Dialight has a strong position in emerging LED lighting markets and a high
quality Components business. The Board remains focussed on pursuing a corporate
strategy that will continue to deliver sustained growth in shareholder value and
to this end, has initiated a broad ranging review of all the Group's businesses.

The full results for the year ended 31 December 2007 will be announced on 3
March 2008.
