How to change the rear indicator on a Peugeot 308 SW

This is not as explained in the manual.
You can visit and read the link below  but its explanation might not be clear. If the assembly is stiff to come off you may doubt your advice.

So, read the link first http://wiki.answers.com/Q/How_do_you_change_the_rear_indicator_bulb_on_a_Peugeot_308_SW

and then read this.

You DON'T TWIST THE ASSEMBLY. Pull it out straight from the rear of the car. Wiggle it about and pull it backwards in the direction of the screws that were extracted.
You can use a screwdriver, though I didn't.
Pull from the large black area of the assembly. Don't fiddle with the red portion that is shown in this photograph.

This photo shows how the thin part of the assembly it secured to the car. It is not in tight. It comes out very easily when you pull the assemble away from the car.
