I can't get pics right now, I left to work out of town. I mounted them below the bumper using the bolts holding on the bumper facia, same place I've seen a lot of people mount them on here.
As far as reflection and being too bright goes I ruled that out by covering the lights, and I also tried it in the middle of the day with nothing around the truck.
Although you got me thinking now... Maybe it could be interference??? These lights I have are square 9 LED high intensity lights made by Maxima. I have a set on just about everything I own that is 12v. They put off a very audible high pitch squealing while they are on. Maybe the sound that the lights make could screw with the park assist??? This is the first vehicle I've had with back up sensors. I assume they use some sort of sound wave or sonar?
The lights are still mounted to the truck. When I get home I will put an extra truck battery I have in the bed. And use it to power the lights..if I touch the wires to the battery and it makes my park assist go crazy again..... Then I will have to try different lights.
Sounds crazy, but it might be the issue..
Thanks for your input Steve. I'll post what I find out.
