I changed my 2004 Toyota Prius drivers side headlight yesterday, and now when I go to drive it I get the Red triangle of death and the ((!)) symbol with the middle console mentioning a problem. iPhone ?
So that means you had things unplugged in the front bumper cover pulled back to get that headlight out so something is unplugged not connected so on and so forth what is your codes? Or you have no way to check? The triangles on is telling you something You're riding with the door not fully closed? If it's something undone it should be fairly easy to spot and or remember wear this might have happened.
