These small, water-activated strobes also attract squid which signal each other using pulses of light. This theory is why swordfish are attracted to lights.
5-10-20 Packs of Pro.strobe/disco led swordfish daylights. By far the most effective style. Flashes between red, green, blue and white, then changes flash times.
Also great as a squid attractant in the water while jigging. Good for placing on bigger deep drop jigs. Especially good for octo style jigs.
Waterproof design, knock proof, anti rust, explosion proof.
