I previously used another set of bar end lights, but they were not meant for drop bars, as the light beam is mainly directed out from the side windows. Those lights are actually meant for flat handlebars, which will position the light in such a way that the bright beam shines out from the side window towards the rear.
This time, I got the proper bar end lights for drop bars.
Simple packaging, at a not so cheap price.
Only 33 grams for a pair! Can add on to your road bike without increasing the weight much.
Light beam mainly shines out from the window on top, although it is still visible from the side window.
Uses 1xAAA battery each. I prefer it over the use of small button cells.
Simple addition to the bike, quite useful in making the bike look wider, and hopefully vehicles will give you a wider berth when overtaking.
Some pictures to show the lights in action:
Rear view of the bike, without bar end lights.
With bar end lights turned on. Slightly more visible, but not by much, unless it is dark.
Another view from the rear, without the bar end lights.
With the bar end lights turned on. They are not very visible, perhaps because my main rear light is so bright!
Meanwhile, the previous bar end lights are not wasted. They have been installed on the Carry Me instead!
