Well, sounds like this works for you in your situation, but:
1) OP is talking about fog - vest is virtually useless except for close range
2) what works for you (i.e. minimal active lighting) may not be compliant with the laws in many places, and, quite frankly is probably less than sufficient for what many commuters find works for them.
3) not all lighting requires batteries. dynamo lighting has come a long way in the last 10 years.
4) Use rechargeables for those battery-powered blinkies. I've been using the same batteries for 5 years for mine.
