Magicshine MJ-6275 Extension Cable

Useful and must-have for helmet-mounted lights

Good quality, stout cable and connector. Adds a ton of flexibility for battery location but this should really be included with lights like the MJ900S whose short cable is a bit limiting (even for a slight bump in price). The extension is the perfect length for me to carry the battery in a waist pack with the cable run inside my jacket up to the helmet-mounted light.

Excellent
