I started with my reverse lights as these were my main reason for wanting better lights.
I bought these http://www.ebay.com.au/itm/130978727995?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649off ebay for $6 each and free (like 20 business day) shipping, but being so cheap i wasn't bothered if they showed up or not, but they did

Installation
To install the lights all you have to do is go into the boot and pull the grey tab off the tail lights case by squeezing the tabs. to take the current bulb out push down on it and twist anti-clockwise and it'll push itself out. VERY simple procedure. (sorry no pics for this, it is self explanatory.) and just reversal to put new bulb in. click the grey tab back in place and it's all done.
Pics
a comparison between Stock and LED (Sorry for quality but you can get the idea)

The difference between the sets of bulbs... Stock

LED

I was already impressed with the look aesthetically but when i got back onto the computer and noticed the difference in light, i was amazed.
This photo was taken by placing my camera (iphone) on the edge of the boot, just to compare how much difference there was in the effectiveness of the lights.

LED

And also just a photo to show the effectiveness from the drivers seat.

No photo's of this - But when on the focused light does not fill the full circle of the reverse light, so there is a clear circle of the focused light. like a small circle of light within a larger circle (the clear lens) - Definitely not a deal breaker.
Outcome - Definitely worth it.
