Using alternative light sources during crime scene investigation significantly enhances the visibility of certain biological fluids, such as blood or bodily fluids, that may not be readily visible under regular lighting conditions. These alternative light sources operate at specific wavelengths that can reveal the presence of these biological materials by causing them to fluoresce or become more apparent against the surrounding surfaces. This capability is crucial in crime scene investigations because it allows investigators to detect evidence that could be vital for solving a case, especially in situations where fluids have been cleaned or are otherwise obscured.

Alternative lighting can also have other benefits, such as revealing hidden fingerprints or reducing glare, but the primary advantage lies in its ability to make biological fluids more detectable. This use of specialized lighting is a vital technique for collecting evidence thoroughly and accurately.
