Probably. When your ballasts start up they draw between 6 to10+ amps of current (per ballast) depending on the manufacturer's specs. Your stock halogens don't draw nearly that much (55 W / 12 V = 4.58 amps per bulb) which means your stock headlight harness can't handle that much current. Additionally, are your DRL's the headlights? If so that'll cause problems too.
