Southern Vectis is urging its passengers - particularly in more rural areas - to ensure drivers can see them when they are waiting at stops.
As winter approaches, and with the clocks going back this month, more journeys will be made in the dark.
So the bus operator is keen to ensure drivers can see those wishing to board.
“Not all bus stops across the Isle of Wight are lit - especially the ones in more rural areas,” said Southern Vectis head of communications, Nikki Honer.
“Passengers who are wearing dark clothes and standing still while waiting for their bus may not be seen by our drivers.
“We ask that people help by shining a light onto the road, and gradually rotating it as the bus approaches - being careful not to shine it into the driver’s eyes.
“Many people have a torch on their phones, but we understand that not everybody is able to make themselves seen.
"Our drivers will still pay extra attention to help ensure customers are able to board during the darker mornings and evenings.”
Southern Vectis customers are reminded that the clocks will go back on Sunday 27 October.
