So, here is what you need to get started:
- The LEDS with your favorite colors (4 LEDS for the indicators, 2 for the central radio/temperature/hour display, 1 for the klima AC console and 1 for the lighter, TOTAL = 8 LEDS)
- A screwdrivers set, both + and – screwdrivers.
1. The speed, RPM, water, fuel indicators:The red dots in the following images represent the positions of the screws. You need to remove all those screws.




After you have removed the screws, remove the 2 plastic masks represented with red and green in the image.

Switch the lever represented with the white color in the image to loosen up the speed, RPM indicators. Extract the part and replace the normal lights with your new color LEDS.

ATTENTION!!! Be careful to get the polarity right, otherwise you will have to redo the entire thing again. You can try to put the indicators back in again, switch the lever again and turn on the car headlights to see if all your LEDs are working. Once you got that right, go ahead and put everything back the way they were and put in the screws.
2. Klima / AC control console:
Grab the central lever (for the air intensity) with your fingers and pull with force and attention at the same time. You need to pull it with attention to avoid breaking it.



Once you have pulled out the air intensity button, proceed to replace the light with your new LEDS. You should use some pincers / tweezers if you have big fingers :D. After this, find the right position and insert the air intensity lever back to its place.


PLEASE NOTE!!! In the picture I already have the blue LED in because I already changed those.
3. Lighter:
Watch my video "Astra G LED Tuning Tutorial" from YouTube to see how you should proceed to get to the lighter light to change the LED. Once you have removed the two plastic pieces, locate the light bulb, easily squeeze out the lighter and change the light bulb with your new LED. After that, obviously, put everything back in place.

4. Central console (hour, radio, temperature, date display):
First of all take a moment and think a lot if you want to change those light bulbs too, because of the hard work involved. In case you decide to change them, here is what you have to do.
In the first image, the blue dots represent the screw positions. As you can see, you need to do the following things:
Remove your stereo and then remove the screw behind it.
Remove the plastic cover from the free space under the stereo: you need to release the 4 clams and then remove the screw behind it.

Remove the 4 arrow – triangle button (the one you use for emergencies or car problems). You need two (2) straight screwdrivers; insert them on both sides of the triangle button and extract it easily. After that, remove the 2 air vents (Image 19). There should be some other screws behind the air vents, after removing those, remove the entire big plastic piece (image 20).



Once you have done this, look behind the display and change the light bulbs with the new LEDs. When you have finished, put everything back in order and you're done!
Hope this was of good help to all those of you interested in modifying your interior lights. Cheers!
