Hi,
i have a shelby gt500 2007, i did changed the halogen headlights with 2008 gt500 xenon headlights in may 2015 and had to add relays and contacters, the car was fine till July 2017. When i leave the car locked or not the headlight start to turn on by it self and will do that till the battery flat, i just replaced the alternator, new battery, all the wires added to the headlights have been replaced and checked, also i checked the voltage and it shows no leak in electricity. Every thing i had think about i checked it and still have the problem.

Does anyone had this problem or have any idea what to do or what to check ???

The car location in UK

Relays going bad?

What wire/wires did you tap into for the relays, are you sure they do not stay when car is off?

Full circuit electric wires and the car been seen by 5 electrician garage, all of them said nothing wrong with the wires circuit and the car been well for more than 2 years from when the wires first add to the car. New relays were fitted this week
