when i changed mine, i loosened the headlamps to gain a bit more room then had to move the retainer/clip to one side on the back and the black cover on the back just pulled off. Was then able to access all bulbs to change. Ended up changing all to get rid of the amber ligh bulbs to super white. Also changed the idicator bulbs to the 'soap bubble' diadem bulbs, looks ace now.
