LED Colour Light Signal

Signal House Ltd has achieved approval from Network Rail for its range of LED Colour Light Signals. A copy of our Product Approval Certificate no PA05/03007 (issue 3) can be viewed here (file size 1.08MB).

The SHL range of LED colour light signals is designed for use with multi-aspect signalling systems and is available in the full range of cases sizes to accommodate 1, 2, 3 or 4 individual aspects. For more information on the LED Colour Light Signal please download our data sheets below, or please contact us (pricing information is also available).

Purchase of LED Colour Lights for the Network Rail controlled infrastructure is via the terms and conditions of the Network Rail issued framework agreement for the supply of LED signal head materials (SYN02).

Other benefits include:

Massive whole life cost benefit through high reliability and improved asset life. The minimum expected aspect life is 10 years.

Independently replaceable aspects meaning that replacement is only required for the aspect that has failed (and not any of the others). Aspects can be easily replaced within a 9 minute period.

Mimic of ‘first filament failure’ – the signal aspects will mimic a first filament failure when the optical output reaches a certain level. This gives a warning that the aspect requires replacement within a 3-6 month period. This removes any ‘guesswork’ in any aspect replacement programme.
