To replace the side light bulbs.
If you follow the link richw911 posted on page 1 it will be easy, and all the parts go back on easy and line up/profile fine.
The side light bulb itself can be pulled out but you need to squeeze the tangs either side of the bulb holder at the same time, I used long nose pliers, I suppose you could use some tweezers if you attempt it without removing the bumper.
It may take you longer than 10 mins the first time, but it really is not too difficult or time consuming to remove the front bumper.
To replace the indicator bulbs I do not remove the bumper, but it is advised to wear gloves as your hands will suffer, it is quite a fiddley job.
If you have large hands, remove the bumper.
