So, I have this tiny niggle...
All my cluster warning lamps work, but those for the indicators just don't show in the daytime and it is a little irritating. They are fine after dusk.
I've read all the stuff warning against over-powered lamps, but it seems odd to me that MB would have thought it ok for these lamps not to be visible in the daytime.
So my questions are:
1 Is it possible that the 12v 1.2 w lamps fitted in my car are actually not the correct spec. and that they might originally have been higher wattage?
2 Is it possible that the right spec. lamps just wear out and dim over time?
3 Given that the lamps are on-off indicators, that don't glow "on" is there really any risk from a slightly higher wattage? I ask this not least because immediately next to each of the indicator lamps sits on the 3 main dial lamps which are 3W (MB N072601 012240) and I can't imagine the fittings or local PCB components are that different?
PFS Parts (link below), supply the following OEM instrument bulbs:
12v 1.2W (as now) (MB N000000 003651, PFM902342)
12v 1.3W (MB N000000 000977, PFM90236 - think PFM might have missed a digit there...)
12v 1.5W (MB N910141 000000, PFM902341)
12v 2.0W (MB N000000 002453, PFM902347)
I thought I'd experiment with these, unless it's really not a good idea - assuming a match on the twist-lock component, of course.
My other bug-bear is my missing vent-lamp and wiring on the N/S, the entirety of which is just plain missing. I am looking for a recon. bulb-holder plus wiring at the moment.
Mission is to have everything working on the car, without obsessing about a concourse restoration!
Sorry about that - a lot of words for two pesky little lamp bulbs!
