Lights are on when car is off

SOURCE: Warning light on dash says "Lights" but all lights work?

Disconnect vehicle battery for 2 minutes, reconnect battery and vehicle will do a system check, if all is ok the light will go out.

there's a problem on your alarm sensor, try to go to your nearest dealer for that matter.

SOURCE: The ABS,Brake Light,Battery light go on and off sporadically while driving.Does this indicate an Alternator failure or a sensor/computer problem?

yes it's most likely a alternator problem,usually the internal diode bridge breaks causing all lights you mentioned to come on,if this happens at a idle open the hood and remove green connector on alt.if lights go out you've found the problem

Check your alternator as it sounds like it may be starting to go. The battery light trips when it detects an issue with the charging system. Very rarely, the battery light can trip if there's an issue with the PCM, but this is very rare.

Take a voltmeter with the car off and measure the voltage on the leads of the batter, should be around 12V+-.2. With the car running, measure again and this time it should read 13V-14V. If it does read 13V-14V then it means that the alternator is working. If it is below 12V, then it means your alternator is not charging the battery properly. If it's above 14V, then it means your alternator is overcharging and damaging the battery.

The problem with the DRL issue describd in the above posts is the DRl module(it needs to be replaced). The buzzing relay and intermittent on/off of passenger side DRl are indicators that the module needs to be replaced.
