9V (later marketed as the Electric System or the 9V-powersystem, depending on country) was a voltage standard for electrical components (e.g. motors, lights) in many LEGO sets. It first appeared in 1985 in the Light & Sound series of Town and Space models that featured flashing lights and sirens, and was later expanded to the Monorail sets in 1990.

The power came from a battery box with one 9V battery (e.g. or later with 6x 1.5V batteries (TECHNIC, Basic). The 9V system sought to address the major weakness with the preceding 4.5V and 12V systems which was the pinned plug connectors that were prone to coming loose or the wires that would eventually fracture and fail after heavy use. The new system used special bricks that contained conductive elements built into the studs which were connected more positively and were more reliable over long periods of use. Wired connections were still used whenever power had to be transmitted through awkward routes, but the terminations used the conductive brick connectors in place of the pinned plugs.

TECHNIC moved over to the 9V system in 1990, with Trains making the change the following year in 1991. The Trains theme was the only application of 9V that was powered by a mains DC Transformer and special metal conducting rails for 9V Trains (without any add-on centre conductor rails that were used by the earlier 12V Trains system). Controversially however the 9V Trains system lost most of the accessories of the 12V system such as remote controlled signals, points and lights.
