Cole Hersee Indicator Lights & Engine Warning Alarms

For nearly a century, Cole Hersee has been providing reliable world class switching products to the automotive, marine and trucking industries since 1924, earning a reputation for electrical components that withstand the demanding conditions of heavy-duty vehicle applications. Within the indicator lights and engine warning alarms category, Cole Hersee has established itself as a manufacturer of robust warning systems designed to alert operators to critical engine conditions before minor issues become catastrophic failures.

Dual Warning Systems for Critical Engine Protection

Cole Hersee offers a wide range of Warning Devices, Pilot Lights, Panel Lamps & Sockets which include panel, map and utility lamps, are constructed of steel or brass plating to resist corrosion. The company's approach to engine warning systems emphasizes redundancy and reliability. Rugged combination warning light and buzzer give audible and visible alert, ensuring that critical conditions like low oil pressure or high engine temperature don't go unnoticed in noisy operating environments. The combination of visual LED indicators and electromechanical buzzers provides failsafe alerts that can save engines from permanent damage.

Comprehensive Engine Monitoring Kits

Cole Hersee's engineering extends beyond individual components to complete monitoring solutions. Alarm Buzzers, and warning kits include universal buzzers, dual alarms, and dual rate alarms that sound a warning for two different hazardous conditions. Kits are available for low air pressure, low oil pressure/high engine temperature. Their engine warning kits bundle sensors, switches, and alarms into integrated packages that continuously monitor critical parameters. Kit Includes warning buzzer, oil pressure switch and temperature switch. Switches continually monitor engine oil pressure and engine coolant temperature, providing comprehensive protection in a single installation.

Heavy-Duty Construction for Harsh Environments

What sets Cole Hersee's indicator lights and warning alarms apart is their construction quality. Universal application: use with any electrical switch. Red lens, long-life led. The company's products feature long-life LED technology that outlasts traditional incandescent bulbs while drawing less current—a critical consideration in 12V and 24V electrical systems where every amp matters. The corrosion-resistant housings and sealed components reflect Cole Hersee's understanding that these warning devices must function reliably in marine spray, engine compartment heat, heavy equipment vibration, and the dust and grime of commercial vehicle operation.

Universal Compatibility and Professional-Grade Reliability

Littelfuse Alarms and Accessories are designed for universal applications within harsh environments. Their features are designed for ease-of-installation and extended product lifecycle. Cole Hersee warning devices work with both grounded and non-grounded switch configurations, making them adaptable to a wide range of vehicle electrical architectures. This universal compatibility, combined with straightforward installation and proven durability, makes Cole Hersee indicator lights and engine warning alarms the choice of equipment manufacturers, fleet managers, and technicians who need warning systems that will still be alerting operators years down the road.
