creating a c4 blinking light material

so I am currently working on a basic mcom. It will be just a barrle with some c4 on it. Nothing too special, but I would like to have the c4 with an antenna and a blinking light. I know how to model it, but how do I create a blinking effekt?
So I found , but I am quite unsure how consuming this is in comparision to make it inside a BP…
Thank you very much in advance!
I will attach a pic of the basic c4 without antenna and light…
