its not that bad. i took the light completely off the car and spent time doing it
start from the top and work down one part at a time- when you get to the indicator/ reverse light use a hair dryer and pull the stuff outwards that way it'll stretch and you can poke it into position with your finger
hard to explain what I mean but it's essential you use the hairdryer or it'll snap like mine did
sure it could be done in 10 mins if you were used to doing it and it was a simple shape.
if you were to do the front lights it'd take about 2 minutes at most lol
