LED Warning Beacons and Work Lights Guide — Trucks, Machinery and Trailers

Why LED Over Traditional Halogen Beacons?

LED warning lights have largely replaced halogen beacons in commercial, agricultural, and industrial applications. The reasons are practical:

• Lower power draw — critical on 24V machinery with tight electrical budgets
• Longer lifespan — LEDs last 30,000–50,000 hours vs 1,000–2,000 for halogen bulbs
• Brighter output — LEDs produce more visible light per watt
• No warm-up time — instant full brightness
• Vibration resistant — no filaments to break on rough terrain

Warning Beacons — Fixed, Flexible, and Magnetic

Flexible LED Beacon (60 LED)

A flexible beacon mounts via an adjustable metal base that bolts to any surface. The flexible neck allows the head to be angled for maximum visibility. With 60 LEDs and three flash modes, it suits trucks, forklifts, tractors, and plant equipment on 12V or 24V systems.

Best for: Permanent mounting on machinery, agricultural equipment, and site vehicles.

Magnetic Roof Beacon

A compact beacon with a strong magnetic base for instant roof-top mounting. No drilling or permanent installation — ideal for vehicles that need temporary warning lighting.

Best for: Tradies, escort vehicles, temporary site use, safety compliance jobs.

LED Side Marker and Clearance Lights

Side marker lights are legally required on trucks, trailers, vans, and caravans over a certain length in Australia.

Choosing the right colour:

• Amber — front and side markers
• Red — rear markers and clearance lights
• White — front clearance lights (some applications)

Auto Relay stocks 5-piece and 8-piece packs in amber, red, and white — all 12V/24V compatible for universal fitment across trucks, trailers, buses, and caravans.

LED Light Bars — Spot, Flood, or Combo?

A 60W LED light bar provides powerful auxiliary illumination for off-road, work, and driving applications.

• Spot — narrow, long-distance beam. Best for high-speed driving or spotlighting.
• Flood — wide, short-distance beam. Best for work lighting and reversing.
• Combo — dual rows with both beam types. Most versatile for general use.

12V vs 24V — Does It Matter?

Most Auto Relay LED lighting products work on both 12V and 24V systems — always check the product listing to confirm.

• Cars, utes, and caravans typically run 12V
• Trucks, buses, and heavy machinery typically run 24V

A 12V-only light connected to a 24V system will be destroyed immediately. Always verify before connecting.
