Did You Know - Street Lamps Edition
This Is Why Street Lights Are Orange
It's one of those things you might never have even considered, but there's a very simple reason why street lights emit orange light - and why white light is becoming more and more popular
While researching a recent article on the evolution of headlights, I began reading about ‘selective yellow,’ which is the official name for yellow headlights. The reason they’re seen as advantageous is that they remove the blue to violet wavelengths from the projected light - human eyesight struggles to process these colours, which are the cause for dazzle and glare while driving in the rain and snow at night. By removing the blue-violet wavelengths and viewing the road in yellow light, you can see about 15 per cent less, but the effect of this isn’t so bad since the perceived quality of your vision is improved.
After further research I discovered that the reason street lamps are yellow is actually far more simple than that: orange light is cheaper to produce.

I'd Like To Drive This Lil' Rocket
Audi SQ5 TDI Plus packs more potent punch
The new Audi SQ5 TDI Plus upgrades on the existing version with 27 more horsepower and nearly 37 pound-feet more torque. The six-cylinder twin-turbo diesel engine now cranks out 340 hp and a mountainous 516 lb-ft.
Burning that midnight oil will rocket the SQ5 TDI Plus to 62 from a standstill in 5.1 seconds and on to an electronically limited top speed of 155 miles per hour. All the while it will return the equivalent of 35.6 miles per gallon of diesel fuel. Compared to the gasoline version offered Stateside, the TDI Plus now produces nearly as much power but way more torque. Performance figures are now nearly identical, but the TDI Plus uses less of the (typically) cheaper fuel.
