Question by Martin Wood
11 November 2013

Q I would like to create a flashing 1.8mm LED tail lamp on a model railway truck. I propose to power this with the coin cell type battery, (2 x 1.5v) will this unit work? I am also wishing to create a lvel crossing warning light with 2 alternate flashing LED's, could I also use this component?
A Hi Martin, thanks for your question. This component can be used to make the LEDs flash. We also offer flashing LEDs which have the IC built in to make them flash independently: A 3mm version and 5mm version.
