I noticed on my 1983 500 sl that the left turnsignal dash indicator does not blink, while the right one does. I'm hoping that it is only a bulb. Both actual turn signals work. How hard is it to get to these bulbs? Also, the glove box lamp and under dash lamps don't light up. The ones above the visors do though. Maybe these are just bulbs too? Hopefully? Can I just go to any autoparts store and by these buly replacements, or do I have to go to the dealor?
Thank you
