Not exactly light, but made this 8-ton Protomek for scouting purposes. 3 tons for the engine so it can move 7/11, almost 1 ton for armor, 1.5 tons of equipment (full-size Beagle Probe, plus Recon Camera), a half ton for a single weapon, and 750 kg for the heat sinks. No Jump capacity, and really thin armor.
