1987 300SE Euro. Judging by the accuracy of the clock in mine, one would think this is a Swiss car.

I noticed that STRIFE repairs clusters so I am expanding - not highjacking.. - the thread to ask about clusters in general. Hope nobody minds.

All the gauges on my cluster work properly , however at nighttime the light is quite dim. I did replace the bulbs and that helped a little. Would replacing (the old but working ) dimmer improve things ? Basically , is a dimmer a "work or no work" thingy - or does it become less effective after many years ?
TIA
