I have a 2002 P650. I have installed the 6062A bulbs from NAPA. Now I notice at higher speeds a rythmic boggle, as if someone is turning off the ign. switch momentarily, this goes away with the headlights off. Anyone have any ideas? THANKS!!

 

The stock bulbs are 45 wattts so maybe there isn't enough juice to run the 55/60 watt bulbs. Seems odd that going up 20-25 watts would cause the reg to stutter
