I adopted this philosophy in South Florida in "bike death capital of America". What I also think helps more in bright daylight is bright fluorescent clothing. I use a neon orange reflective vest (like road workers) day and night. Have bright strobes on front and bright red (night zone 8, very bright for day) on rear of helmet. Also run the dynamo front and rear all the time the bike is moving. Only turn off the battery ones day or night on multi path trails (not many of those in South Florida).
