• I thought you were going to ask about stock AE, not some unknown plug and play kit you bought, which I know nothing about.
• The driver delivers a specific voltage and current to the LEDs so adding additional LEDs to the driver can cause issues.
• 2 sets of LEDs sharing a single driver is not a good idea unless it was designed to do so.
• LEDs do not use a ballast, those are for Xenon bulbs so if you have a driver plus an unknown "box" maybe that is causing you problem.
• Are you using a voltmeter to verify the drivers are receiving full battery voltage?
• A schematic of your DIY wiring would be helpful in case something doesn't look right.
• Have you contacted the LED kit supplier with your issue?
