Footprint Light Source

This device is primarily designed for detecting trace evidence, such as footprints, impression marks, bloodstains, and fibers, on floors and walls. It is particularly effective for criminal footprint searches and examinations, as well as tire mark inspections at traffic accident scenes. Its portable and foldable handle design makes it easy to carry and store, enhancing usability in various field investigation environments.

Multi-Purpose Forensic Light Source for Crime and Accident Scenes

This portable forensic illumination device is specifically designed for detecting trace evidence—such as latent footprints, bloodstains, fibers, and impression marks—on various surfaces including floors, tiles, and walls.

Featuring stepless dimming and adjustable color temperature, it enhances the visibility of hard-to-detect evidence under different ambient conditions.

In traffic accident investigations, the device is especially effective for revealing tire marks such as skid, brake, and compression traces—providing valuable insight for collision reconstruction and forensic analysis.

Ideal for forensic professionals, crime scene investigators, and accident reconstruction teams.
