Why LED Work Lights Fail: Seven Places a Cheap Lamp Saves Money
An LED work light rarely fails because the LEDs wear out. It fails because heat is not carried away, a solder joint cracks, the lamp is wired backwards or the lens yellows. Seven places where cheap lamps save money, what each one causes, and what to ask a supplier.
Wig Wag Lights: What They Are, Who May Use Them, and the Legal Amber Option for Work Trucks
Wig wag lights flash a vehicle's headlamps left and right, and most traffic codes keep them for emergency vehicles. How the flasher works, what the federal and state texts say, and how a work truck gets the same alternating signal legally with amber warning lamps.
Work Truck Lights: Five Problems the Body Builder Owns, Not the Chassis Maker
Refuse, service, tow and snow-removal bodies are built on someone else's chassis, and the lamps the body builder adds become the body builder's responsibility. Five problems that follow from that, and what to put in the supplier brief.
Excavator Work Lights by Position: What Each of the Six Mounts Needs
Boom, cab roof, counterweight, side, beacon and floodlight: an excavator's six lamp positions each face a different job and a different way of failing. What to specify for each, with the output band and the test to ask for.
Infrared Lights for Cameras Are Rated in Watts, Not Lumens
Cameras on excavators and forklifts need light at night, and the lumen figure on every work lamp cannot describe it. What to check on the camera first, which wavelength to choose, and what number to ask for instead.
Sealed Beam Trade Numbers Fix the Hole, Not the Beam
A sealed beam carries two numbering systems that look alike. A PAR number is a diameter you can calculate. A trade number is an interchangeable outline you have to look up, and neither one settles the beam.
The SMV Triangle and the Amber Lamps Do Two Different Jobs
The orange triangle and the flashing amber lamps answer to different statutes and satisfy different requirements. Minnesota and Ohio both prove it, and they draw the lines in different places.
Is 3,000 Lumens Enough for a Work Light? The Spec That Actually Governs Is Lux
Lumens describe the lamp; foot-candles describe the ground. Our own 40 W lamps run from 2,400 to 4,800 lumens, so neither number answers the question. Here is the arithmetic that does.
Trailer Light Wire Colours Are a Convention, Not a Standard
Three wire colours change meaning between a four-pin and a seven-pin trailer connector, inside one manufacturer's own published diagrams. The connector is the authority, not the colour.
