Yesterday I got the "Check Lights" malfunction and it turned out to be the one of the "not so obvious" license light bulbs. I did replace both of them and put this DIY together in case one might need it later on. Cheers.

Are you sure you can't access them from outside? On the wagon, there are 2 metal screws that hold the plastic. Unscrew them, pop the plastic off and replace the bulb. 2 minutes tops!
hehe it should really be MA-E320 ;-) so it reads wrong .... but nowhere close to my real name. Sergio, I am sure you cannot replace them from the outside as there is no way to take out the plastic molding without removing the nut from the center bolt from the inside. P
Only two thing are infinite, the universe and human stupidity, and I'm not so sure about the former.

I tried three times to get that damm outside lid off with no success and have been driving with only one plate bulb for some time. Great to see this DIY that I will do tomorrow....Thanks
