Probably so.  But, they're still considerably brighter than the 6V sealed 
beams the car used to have, the 12V sealed beams on my '70 T3, *or* the 12V 
H4s on my wife's '89 Cabriolet, though the latter may be due to the Beetle's 
Hella H4s vs. the Cabriolet's EMPI H4s.  The lights did get brighter when I 
replaced the wiring on the headlight circuit...
