id advise everyone to go for the mini ballast hid kits, mine were so simple to fix, the actual ballact i drilled on to the back of the original covers and they fit quite well.
the n/s side is a bit more difficult, but i took out the battery completely, this made it so easy.
you can all see from the pics, the massive improvement.
for £57 i would recommend this mod to everyone as a must. the only down fall is when i get into my wifes toyota starlet, its pitch black,
im not fitting a hid kit to a r reg starlet...lol
