In recent years, the use of signal lights has been increasing across many industries. In the construction sector, demand has particularly grown alongside large-scale projects such as high-speed rail, shopping malls, and high-rise buildings. At construction sites, strict safety measures are required by both public and private sectors, making signal lights indispensable.

This article presents the features and applications of flashing Indicators “GL7 / GL7T” and rotating Beacon “GF7”, all designed for outdoor and harsh-environment use.

High-Durability Signal lights for Outdoor and Construction Work

At sites where safety and efficiency are critical, highly visible warning signals are essential. The GL7, GL7T, and GF7 provide the following key features:

All models feature IP69K-rated waterproof and dustproof performance, along with vibration resistance up to 110 m/s² and shock resistance up to 1000 m/s². These robust characteristics ensure dependable long-term use, even under the toughest construction-site conditions.

【Features of Each Signal Light】
■ GL7 (Flashing Indicator)
Specifically engineered for construction machinery, forklifts, and compact mobile equipment, the lead-wire control ensures reliable performance even in dusty, wet, and vibration-prone outdoor conditions.

■ GL7T (Flashing Indicator)
This model inherits the proven durability of the GL7 while adopting a slimmer profile. The light-emitting surface is positioned on top for space-saving installation and ensures clear visibility even when mounted at low heights or on vertical surfaces. Status indication is conveyed not only by color but also by flash patterns for enhanced color-blind accessibility.

■ GF7 (Rotating beacon)
Inheriting the robust design of the GL7 series, this model employs LED control to produce a 360° simulated rotation effect. Designed for 48V DC operation, it performs reliably in both indoor and outdoor environments. Its compact design makes it ideal for small construction machinery and forklifts. Available exclusively in amber (yellow), it delivers a highly effective alerting effect.

All three models are also available with a magnetic mount, enabling easy installation without drilling.

Applications of Signal Lights on Construction Sites

Construction sites involve numerous pieces of equipment, machinery, and personnel, making clear and immediate visual communication essential. Using signal lights provides the following key advantages:

■ Accident Prevention: Clearly indicates moving machinery and hazardous areas, helping to protect workers from potential risks
■ Enhanced Safety Standards: Contributes to higher safety compliance on both public and private construction sites.

【Application Examples】
GL7 (Flashing Signal Light)
Installed on forklifts and compact construction machinery to display operational status in three colors. Compact design fits tight spaces.

GL7T (Flashing Signal Light)
Ideal for locations requiring visibility at low angles, such as near workers or forklift entry points.

GF7 (Rotating beacon)
Mounted on forklifts and construction machinery to provide a 360° rotational warning signal visible from multiple directions. Resistant to dust, water, and vibration, and suitable for compact spaces.
