                                 Trading Update


Dialight plc, the UK based leader in Applied LED Technology, announces the
following Trading Update.

Dialight consists of two business segments:

  • Signals / Illumination which includes Traffic and Rail Signals,
    Obstruction Lights and the new Solid State Lighting (LED) products of the
    Group

  • Components comprising indication products and electromagnetic disconnects

The Signals / Illumination business, the core activity of the Group, continues
to have excellent growth prospects and is performing well, as the market for LED
lighting gains greater acceptance.  Overall the performance of this division
remains in line with our expectations.

Since our results in early March, our experience to date of order intake in the
Components division remains disappointing and has continued at below 2006
levels.  We now expect this trend to continue for the remainder of the year.
Furthermore, a Group wide programme to reduce the cost of materials saw some
slippage in implementation but is now on track to deliver the expected savings
in the second half.  Accordingly, we have revised our expectations and
anticipate the combination of these factors over the full year will affect
adversely the Group's pre-tax profit by approximately £1.3 million.
