Dialight consists of two business segments:- O Signals/Illumination which includes Traffic and Rail Signals, Obstruction Lights and the new product area of Solid State Lighting O Components comprising Light Emitting Diode ('LED') Indication Components and Electromagnetic Disconnects ('smart' meter disconnect switches) Highlights • Orders for Signals/ Illumination showing continued double digit growth • Strong order intake for Meter Disconnect product • Indication Components continues to perform well • Sale of Indication Business on track • Margins stable in spite of inflationary pressure • Overall trading in line with expectations Current trading Dialight has had an encouraging start to 2008. Orders for the Signals/ Illumination segment are robust and would support continued double digit growth across each of our product lines. In particular, our European Traffic business has had a strong start to the year and the North American Traffic business is benefitting from shipments of the previously announced contract for Miami Dade County in Florida. Sales of Obstruction Lights into the North American Wind Tower market continues to gain momentum. Our LED Indication product lines have shown good solid performance with order intake at a similar rate to the second half of 2007. In spite of the talk of recession in the North American market, sentiment from our customers and distributors is that business is still cautiously positive. The Dialight BLP Meter Disconnect business has had a good start with the $4,000,000 blanket order received in the first quarter from one major US meter manufacturer and production orders received from another US meter manufacturer. This segment should exhibit significant growth in the second half of 2008. While the much published price pressures on commodities have been apparent in our purchased materials, cost reduction is an ongoing activity within Dialight and in spite of those pressures, we have been able to maintain and in some cases to improve our margins. In March we announced that we would pursue the possible sale of our LED Indication business and have commenced a formal sale process with our financial advisors. The process is progressing in line with our intentions. In summary, Dialight has had a good start to the year and trading is in line with expectations. The Board remains confident in the prospects for the current year.
