I have installed LED white lights to my GS300!
Simply follow tigerfish's guide to removing dash and when you get to the following picture, remove the 8 bulbs that have blue holders and are in the holes as shown below

These are the main display bulbs that need changing....
You need the following bulbs (286/T5)
[url="https://www.crazyleds.co.uk/home.php?cat=73"]Crazy LEDS[/url] and select which colour you want...
I purchased 10x white ones for £7ish delivered (£1.50 delivery)
Now, heres the tricky part, you have to pull out the bulb from the holder...I used a small screwdriver to gently prize at the bottom of the bulb and eventually I did all 8. Its good to get 10 bulbs as its good to have a few spares!
Ok So now insert the LEDS into the holders, making sure you know which way they go in
(I remembered which way by simply remembering which way the holder went in! As in "toshiba down, or up")
You will see this when you put them in.
Now, I put all the LEDS in, then screwed in 1 or 2 holes of the board so its secure, then I put the plastic white cover on, this is to protect the components as you are about to put 12V through the dash!
Have the wheel down as much as possible and forward when inserting dash.
I distinguished that the middle orange cable supplies the illumination to the dash, the rest are for warning lights, petrol, oil and needles, so you need to disconnect everything and simply use the orange middle cable to check.
As LEDS have polarity, you have to keep inserting the dash and swapping the LEDS around and making sure the connectors are making a firm connection with the holders,
I did this around 10 times as 1 LED did not work, so I simply replaced it (see why I bought spares?!)
Now, all connected up, heres some pics!

Unfortunately, the orange mileage indicator is fixed at yellow and cannot be changed
Enjoy!
