With great difficulty. There is a cover under each front wheel arch which has to be removed. There is no room to get your hand in to change the bulb. Ended up taking mine to garage where they first they removed the wheel then eventually removed covering on the arch itself to get to the bulb. It took them an hour. Fortunately they only charged me for the replacement bulb, saying Renault is the worst car ever for replacing from bulbs.
