Hello and welcome to JustAnswer!

If these warning lights came on while driving and it will now not start then I suspect the battery is dead due to the alternator not charging. If the battery light comes on with the engine running it's because charging voltage is abnormally low or high.

What happens when trying to start the engine now?
