For this particular accident, it happened at 7am, so visibility wasn't the issue. The ID tag I suggest is because the family members was only informed around 10pm, more half a day later, coz he couldn't identified.
Side topic : you may not believe the below info of coz, but just some info for anyone who are interested in being as safe as possible, though there are no 100% guarantees.
From a cyclist and driver pov/experience, actually visibility is quite a possible issue at 7AM.
Dont say 7am, even broad day light 10am in also it could be the issue. DRLs and fluorescence under daytime (UV) do help, from studies, but not fully, but it does help at a certain percentage.
Actually didn't wanna post this, but just a few days ago i banged someone (lightly) at exactly that time), at that corner of the cycling track between 1 marina boulevard and Promonitory. I couldn't see him at all and he was probably day dreaming. But all is well, he did not blame me after i explained that i totally could not see him due to his dark clothing. He cannot blame me, i was operating well within the confines of the law.
The issue is that at speed, drivers (or cyclists themselves) cannot react fast enough. The faster the speed, the easier it is to screw up. Remmeber, it is a combination of both party's speed, not only 1 single party.
For my bike for day time i am operating specific lights that are visible under full sunlight conditions.
ie Cygolite Hypershot 350s, multiple units. I have other lights of coz but this particular one would make the user the most visible. These are only used during weekends coz only then would my sessions get past 8am and into around 10am, and sometimes afternoons also i will get out there.
You use at night or even dusk/dawn, sure get scolding, esp in the bloddy irritating modes. It's literally blinding, to say the least.
As tested before, this would give you the best chance vs a PHV driver poking at his mounted mobile phone, it would work ok in such situations. Or on e-bikes poking on their devices (i shared before i nearly kena t-boned by such a bugger before with the right of way for me, now i operate side lights as well)
But not against extreme cases like a drunk driver etc.
