About Relative Visibility of Signal Lights

Pipe/Surface-Mount Flashing Lights

Lights meet NEMA 4X for protection from corrosion and washdowns.

LED bulbs last longer than halogen bulbs and provide years of maintenance-free operation.

The clear replacement lens is intended for use with the white light color.

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).

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.
