I recently changed out my 194 bulbs to what the packaging online said were "Extra Bright"... um, not so much.
New boss same as the old boss. Dim.
So I would recommend what I'm going to do, 'Trust but verify'
Oh, per bd's warning about dimming, the easy work around is to leave an incandescent (original) 194 in a non essential location, i.e. ashtray, wiper switch. It will fake out the rheostat/dimmer by supplying a suitable load to dim.
