Front indicators u need to go through the wheel arch. Side ones u need to get the grille thingo off. an old credit card or trim removal tool wrapped in a microfibre should do the trick. The back, as u would change a bulb plus you need to splice in the resistor and find a place to mount it.
This is the kit i bought.

and yes still very bright during the day. brighter than the stock bulbs by heaps.
edit: no errors at all as the ones in the kit are specifically designed for the VF.
