[General Fiction] Why do terrorist and mad bombers so often make explosive devices with blinking and beeping lights on them?

Because they don't have a Quality Assurance department. They need to be able to verify on the spot that the bomb is working right when they go to plant it (i.e. nothing shifted in transit, none of the wires got tugged loose, the battery is still live, etc), and they need to be able to do so without hauling any extra gear with them. By having a set of status lights (possibly even a timer, if they're feeling saucy) they can rapidly confirm that everything is good to go when they go to plant the bomb; if the bomb fails to blink or beep, then they have one last chance to troubleshoot the problem before having to scrub the job.
