Along with e-bikes becoming the most popular mobility in our daily life, E-bike LED headlight more and more mentioned for getting a safe ride.
No matter the commute, sport, leisure, or transportation, e-bikes will be the most common mobility around us, whereas safety for riders will also be a significant problem we’re facing.
E-bike LED headlights can help a lot on the riding safety, and they are the most important gear on e-bikes for safety in the nighttime, even help during daytime.
Do you know what the real safe headlights for e-bikes are?
We can find some clues from the requirements of UNECE regulations.
Simply speaking, according to the FIGURE C in UNECE R113:
Light beam has been required evenly distributed in a specified area, specific distance and specific beam pattern to ensure a safe vision.
Specific Area(vision range): Which Is Related To How Wide You Can See
You must see lots of headlights emit a round spot that closely 3-5m ahead of the E-bikes, similar as below picture (left).
Riders might concern or even be nervous because you have no idea at all about what exist on your headway, left & right sides.
Compared to BRIGHTSTARTW ‘s headlight emission, you could find out the full vision makes you feel full of secure on the way in darkness.
Specific Distance: Which Is Related To How Far You Can See
Almost all E-moped headlights on the current market are rebuilt from bicycle lights.
They’re actually not bright enough for e-bikes/e-moto which speeds are 25kmh, 45kmh and even higher.
For ensuring safer riding with e-bikes/E-moto, European Union exactly have the standards about headlight for those high speed 45kmh e-bike/e-scooters.
According to UNECE R113 6.1.2 The illumination produced by the headlamp shall be determined by means of a vertical screen set up 25 m forward of the headlamp.
And there’s a required luminous intensity for E-mark class C, the Min luminous intensity of the maximum would be 32 Lux at the 25m distance.
How Important Of Far Light Distance
Let’s see why we make the light emit to farther distance? Check this form below.
25KM/H (6.9 m/sec)
Reaction Time For Danger
45KM/H (12.5 m/sec)
Reaction Time For Danger
|E-mark Class C||25M||
|K-mark||10M||1.45 secs.||0.8 secs.|
|N/A||5M||0.72 secs.||0.4 secs.|
Specific Beam Pattern: Which Is Related To The Driving Safety Of The Opposite
In the regulation, there’re Figures to show how the beam pattern should be.
According to 6.2.1., it states that for a correct aiming the passing beam shall produce a sufficiently sharp “cutoff” to permit a satisfactory visual adjustment with its aid.
A clear cut-off, prevent the mess light above the “cut-off”, which might dazzle the vision and cause accidents from the opposite driving.
For all the light source which are legal on road, the “cut-off” is a necessary and significant quality standard that light have to obey.
Of course, currently the standards regularize the L type approval e-bikes’ LED headlight, excludes L1e-A(pedal e-bikes under 25kmh).
After reading these safety notes of e-bike LED headlights, do you realize the significant meaning of the headlights?
For your & your families’ safety, will you still just want a torch on your bike?
Or you would carefully consider the approved & regulatory compliance light which means quality & safety.
