About Relative Visibility of Signal Lights

Pipe/Surface-Mount Stack Lights

These lights have lenses that snap in and out, so you can easily swap colors or change their position in the stack. They meet NEMA 4X for protection from corrosion and washdowns.

Use the extension pipe and mounting flange to make the light taller (both sold separately).

Use the vertical-mount bracket (sold separately) to mount the light to a vertical surface such as a wall.

Build-Your-Own Stack Lights

Design a stack light with your choice of light pattern and color. Start with a base, then add up to five modules total—twist and lock them together. All components except for replacement bulbs meet NEMA 4X for protection from corrosion and washdowns.

Sound module must be placed in the top position.

Flashing Lights with Buzzer

The buzzer warns workers of hazards even when they’re outside a direct line of sight.

Light intensity is measured in candlepower (cp), which indicates how bright a light appears at a distance. Common examples include a car’s taillights (50 cp), traffic signals (600 cp), headlights (15,000 cp), high beams (50,000 cp), and police car searchlights (150,000 cp).

Revolving Lights with Bell

The revolving motion of the light makes these more visible than flashing lights. The bell alerts workers when they're outside a direct line of sight.
