This has probably been discussed here a zillion times but I am new so let me ask this question again, on my 123 240D 1977 the instrument lights are pretty darn dim to a point that friends riding in the car ask why have I turned my instrument light off.
One MB shop recommends replacing the existing 2W bulbs with 5W, is this a good idea?
My dimmer has been replaced a while back but the new one made no difference.
Appreciate any comments.

Thanks,
Vahe
