I just purchased an HID system however the headlights are not giving enough power to ignite the ballast. I hot wired the ballast directly to the battery and it works fine but wont work when I hook it up directly to the headlight wires. Is there anyway to increase the volts/wattage to the headlights? I have a 2007 Senna. The other thing I noticed is that the headlights do not come on unless I start the engine. My 2001 MV 750 comes on when I turn the key. Did MV change the way the lights come on?
