Hi Greenfield, I've never had problem changing front bulbs, I refuse to pay a garage to do those small things! I've had a few megane's now and they've all been the same, under the bonnet behind the lights there's a circular cap over the bulbs, you just twist that off and the lights then are on a spring like wire which you just push to the side and it open's and then pull the blown bulb out.
Just dont forget to put the cap back on afterwards, I found mind about 2 months later trapped between bonnet and battery!!!
