i agree with JCE
the dealer did me the favour of replacing some bulbs (that was before I was introduced to this group ...) and I ended up with different brightness bulbs in the dash (it was OK in the blue Hi Beam, but the other ones were really irritating, having different brightness orange warning lamps during ignition on ).
Dependant on what your indicator strips look like, replace the bulbs (use the same type of new bulb rating throughout) and your problem should be solved.
Take note that the left side bulbs are in a plastic holder (and a tad more expensive) whilst the right side are not ...
Changing them is a breeze ...
hope it helps - otherwise you should clean (with a light emery) the various contacts on the round connector to clear any deposits that may cause a dimming of warning lights.
