A revolving LED strobe flasher on top of your truck is a great choice. There are few limits to the lighting performance, color or the flexibility to use permanent mounting hardware. Upgrade your truck warning lights now and enjoy peace of mind when your vehicle is on the road.

There's no question that our infrastructure today must handle a volume of traffic never imagined by the original highway planners. Roads are now shared by light cars and heavy trucks. Foremost in transport safety, the use of warning & emergency lights laws mitigates the potential for accidents.

Both local and national officials are scrambling to accommodate the ever increasing flood of traffic. Should they build more roads or repurpose existing infrastructure? Safety is a big issue when small vehicles and large semis share the same roads. Why not stay ahead of the game by using additional lighting to enhance your safety?

Strobe lights are essential to warn other travelers to exercise caution. Truck strobe lights have come a long way. Because of LED technology, you don't have to worry about dead warning lights. What about the cost of outfitting a single truck or even a fleet? The good news is that you now have the option to use an LED strobe flasher warning module for trucks to convert your existing lights into safety strobes. You can choose from a large selection of flash patterns, as well as pick alternating or sync flash.

How does this work? Is it somehow related to the size of the projected image circle? I also noticed that micro4/3 lenses have a "sweet spot" at a lower focal length.

How does focal length affect physical lens size? I noticed that as you go from telephoto to shorter focal lengths, lens size decreases, quite obviously. But around 35mm (?) the trend reverses, and wider angle lenses become bigger and bigger. The Canon 40mm f/2.8 for example is ridiculously small, but the Canon EF 20 mm F2.8 USM is quite huge, again.

It's bad enough to suddenly drive up on an unseen road obstacle. Even more harrowing is rounding a corner when another semi is parked in your lane. The size of your vehicle alone is not enough to alert traffic to potential danger without solid, effective vehicle warning lights; otherwise, you risk serious bodily damage to drivers and passengers, including severe damage to their vehicles.
