I tried this on a customers car. Not a very smart thing to do btw. Wired everything to the parking lights (except the amber wire which went to the blinker of course) and now we are noticing the switchback is not working so well. When the blinker is on, instead of shutting off the white completely it flashes white and amber back and forth. Also there are issues when you turn off the blinker. Sometimes it switches back to white immediately, other times there is a delay, and sometimes no lights at all. Not very happy with this product at the moment. Calling the company to see what they say.
