My commute is all on well-lit busy roads. I have one of those Topeak helmet lights above which I set to flashing, a Solar Storm on one side of the bars set to constant (on low setting) and an Aldi mini LED on the other side of the bars set to flashing.
On the rear I have a ‘holy hand grenade’ set to one row constant and one row flashing as well as a rear light on the mudguard which I set to flashing.
I will also be digging out the flashing reflective armbands and spoke reflectors this weekend as well for the full ‘Christmas tree’ effect 8)
