The CL-1918-1S (single-sided) and CL-1918-1D (double-sided) automotive lighting system trainers utilize the “Moduponent®” design feature which allows unlimited expansion capabilities.
A Moduponent® consists of a clear Plexiglas sheet with components, wiring and socket test points
attached. The Moduponent® is attached to the trainers using disconnect fasteners which allows easy
adaptation and configuration for different applications.
