Like the title says, I need an exterior mount four head light stick in all amber. I'm not picky about brands, but no complete junk (STL). Needs to have an internal flasher and some mounting brackets. I'm not looking to spend a ton, so used is preferred unless you have a great deal on a new one. This will be mounted beneath a rear bumper for dirt racetrack work, so needs to be able to stand up to the elements. Thanks much!
