I noticed 2 bikes last night with problematic rear red light.
First of all I was riding on the PIE at about 11.30pm. Hazy night, so visibility wasn't good.
The first bike I passed by was a madass 125. Rear light was faulty or wasn't there, but rider replaced it with a small blinking light. Problem is - it's too small/slim to be visible from afar.
My first tot was I was riding pass an electric bicycle when I pass the bike in the middle of a expressway.
The second bike was a RVF400 with pillon. Rear bulb faulty, so no light for the back ppl to see. From a distance of about 100m, I can only see a black spot behind a car. The bike has blended into the darkness + haze.
At near midnight drivers are driving fast, so they won't be able to spot the bike until a close distance. In both cases, both bikes are ok to ride in the day, but at night, please ensure your rear light is working and bright enough for ppl to see.
