Replaced almost all indoor lights with warm white LED replacements. Much more energy efficient and also gives a more modern look.
I dont like the look of the blueish white LEDs, these are much better and give a more "usable" light.
Everything can be done at home by yourself, even the big cluster lights. The manual says it needs to be done by the garage / dealer, but save yourself some money and do it yourself!
All lights are either 36mm / 39mm festoon C5W or W5W / T10 Wedge bulbs
