Very easy. Just pull the bulbs straight out (they will be on so may be hot, use some tissue or a cloth if too hot) and pop some w5w led's in. Literally 30 second job.
Already got my led's in (footwell + number plate), richbrook ariel, wind deflectors and carbon ST inlays on. Grabbing some wing mirror caps and wrapping them in carbon soon
Looking good. Sounds like you've been pretty busy already!
