Cyclists need to make sure they are well lit as daylight saving ends, say the Cycling Advocates Network.
But those using super-bright LED lights should avoid dazzling other road users.
"Flashing super-bright bike lights can be a distraction, so keep them aimed low," says CAN spokesperson Patrick Morgan.
The end of daylight saving on Sunday 6 April means it's time for cyclists to check their lights and batteries, says Mr Morgan.
"Some may be caught out by earlier evening twilight, so we all need to be extra careful."
"Cycling offers the ultimate trip: it's a fast and convenient way to get around, while improving your health and saving you money."
"Our message to bikers is to get out there and enjoy the ride, and to remember to use lights whenever visibility is poor."
"For drivers, the message is to look twice for people on bikes, especially at intersections."
Bicyclists, when riding at night, are required to have:
* one or two, white ot yellow front lights. One may flash.
* one or more rear lights, flashing or steady
* lights must be visible from 100m
* pedal reflectors or reflective clothing
