Who uses lighters or matches which are so 19th and 20th century? Bombs with flaming/smoking fuses are so Bugs Bunny. Sophisticated and stylish modern terrorists use electronic ignitors/detonators for their explosives.

Such detonators may be contstructed prior to deployment and concealed in ordinary electronics or constructed in the field from common and unsuspicious articles such as 9V or laptop batteries and low-resistance wire.
