Motorists are being reminded to look behind for bikes before opening their car doors.

Musician Don McGlashan came off his bike when a driver opened a car door in front of him on Valley Road in Auckland.

Community transport manager Matthew Rednall said since a fatal cycling death on Tamaki Drive last year, Auckland Transport has initiated a range of safety measures and is now finalising a new safety campaign called "Be Bright, Be Seen".

The campaign encourages cyclists to wear bright reflective clothing and turn on their bike lights during the darker winter months.

Cycling Advocates' Network (CAN) spokesman Patrick Morgan said today that with daylight saving ending on Sunday morning, cyclists needed to wear brighter gear.

"Bike lights and high-visibility riding gear make you easier to see."

A steady or flashing rear-facing red light, a forward-facing white or orange light, a rear reflector and reflectors on pedals are also recommended.

"I have seen drivers sitting at an intersection do a double take when they see me riding a with a powerful headlight," Mr Morgan said.

"The other great thing about being well-lit is that drivers have plenty of time to give cyclists room when passing."

Mr Morgan advised people to check their batteries as they may need changing.

"Be bright, be safe, be seen," he said.
