Default SyS flashing

When I turn on my lights (All the way, no problem with just parking lights on) I get SYS flashing 3 times every 5 seconds. It did this when the relay was bad which caused one of the headlights to stay down, but this just started recently out of he blue. Both lights pop up, but I get this annoying SYS...???

Car running I assume.. and has been running long enough to charge the battery?

If it detects low voltage and thinks your battery is dying... turning on the headlights could set it off.

I followed the advice, adn replaced my battery with the flashing SYS. With a Sam's club 730 CCA the light is now gone.

Could be an altenator dying. The more accessories you turn on the more power it drains. Check that as well.
