Automatic control of a colour light signal with feather.

Heathcote Electronics's MAS Sequencer RI is shown controlling an Eckon 4 aspect signal with feather. This option has a red or yellow aspect when the secondary route is set to warn the engine driver of a sharp curve. We also have the option to display the full range of aspects for the secondary route. Note that the feather extinguishes when the signal is at red. This is to prevent drivers mistakenly perceiving that a lit feather is an open route even though the signal is at red. For more information visit www.heathcote-electronics.co.uk
