What is the toyota yaris headlight relay location?

In order to find the Toyota Yaris's headlamp relay, You can look to for code H-LP/AMT Relay on a diagram. You should be able to find it in the small relay box found under the hood on the passenger's side of the vehicle. It's a common cause of problems for drivers, as a failing headlight relay can result in intermittent failure or suboptimal lighting conditions of the Yaris's headlights. If You're uncertain that Your relay has failed, You can test it by swapping it with the HTR relay, which is found at the center of the bottom row of the fuse panel located under the dash. If the swap results in Your problem being solved, it's worth the few dollars to pick up a replacement relay; certainly less expensive than new headlamps.
