the side repeaters are easy, slide the lens of the side repeater towards the front of the car, pull the S/R out from the rear of the lens (try not to let the wire fall in!! you'll then probably have to take the wheel arch liner out! use a clothes peg on the wire)
front indicators.... on the back of the headlamps there is a (usually white) locking bar which locks the clips of the indicator to the headlamp.
swivel this out with a small screwdriver then depress the clip of the indicator and push it forwards and out change your fried eggs and put it all back in, not forgetting to return the lock pin back in position!
