Very fiddly. The outer lights are accessed from a hatch under the wheel arch with the steering turned to the side, the inner are under the bonnet with either very small hands or a bit of dismantling to reach the fittings. Really it's a workshop job.
That's for Halogens, if you have Xenon HID then it's certainly a workshop jobHow to change the headlights on the astra twintop design?
Open the bonnet and remove the black rubber bit.
