I have a LS 400 and have had it for 5 years. I had to replace
alternator like a year and a half ago. Now my car is doing
same thing. Woke up other day battery light was on so i
replaced the battery with a new one. It crunk up but then
the battery light was still on. So i drove it to my family
house and it continued to cut off on me. On the dashboard
it says headlight leveling. Can anyone tell me what could it
A battery light on means the charging system is compromised. With the engine on, probe the battery with your multi meter at voltage. You should have a reading around 14V. if not, then it could be the alternator and or the wiring.
