The white in-line LED light module is a feature of some 91mm models and was was introduced in 2002.
It is paired opposite the short version of the inline Phillips screwdriver in most models, or the magnifying glass in the CyberTool Lite & Swisschamp XAVT.
The light unit housing was originally grey, however the most recent versions (2019) have an attractive transparent housing.
The sliding switch can be locked in the on-position or, when in the off-position, pressed down for momentary-on operation.
Later versions (introduction date currently unknown) were brighter than that the original version, with the 2019 version being significantly brighter again.
The unit is powered by two replaceable button cell 3V CR1225 batteries.
