Dead battery at 6am, engine bay's a black hole, and you're fumbling for the right terminal. These Jaycar jumper leads sort that. Each clamp has a built-in LED light so you can see exactly where you're clamping, even in full dark. Rated to 400A for heavy engine starts, and the voltage surge protector sits between your battery and the other car's electronics so a bad connection doesn't cook an ECU. Three metres of lead, clear carry case, batteries included. Toss it in the boot and forget it's there until you need it. Jaycar WH6012
