You must consider the effect of wearing a light coloured helmet according to British Medical Journal.
I did.

"Helmet colour
The main colours of helmet reported by control drivers were black (39.8%), white (30.6%), and red (13.8%). Compared with wearing a black helmet, use of a white helmet was associated with a 24% lower risk (multivariate odds ratio 0.76, 0.57 to 0.99). We found similar associations for red and a combined group of yellow and orange helmets, although these did not achieve standard levels of statistical significance. Self nominated description of “light coloured†helmet compared with “dark coloured†helmet was associated with a 19% lower risk.
Headlight operation
Of the 175 control drivers randomly surveyed at night, 100% were using their headlight. At twilight, 91 (88%) of the 104 control drivers reported having their headlight turned on. Of the 954 control drivers randomly surveyed during the day, 719 (75%) had their headlight turned on—609 (64%) on low beam setting and 92 (10%) on high beam, with 18 (2%) unsure whether high or low beam was used. Overall, voluntary use of headlight in daytime was associated with a 27% lower risk of crash related injury (multivariate odds ratio 0.73, 0.53 to 1.00)."
