When driving at night my headlight flash off and then come back on. Nothing happens in the dash but you can see them go off and then come back on on the road. I have no idea where to start to try and find this problem. Thank you in advance for your reply.

Hi,

Can you get a video of it doing this because I am wondering if they are both doing the same thing equally, and do they flicker or are they a slower blink? Clearly trying to describe this is more difficult then getting a video of it which should get me on the same page as you.

Thanks

I don't have a video. It's not a flicker and it doesn't seem to happen when in park, also it doesn't happen when they are in the auto mode (switch) only in the on mode.

Okay. More than likely it is the switch then. If it only does it when they are in the on position and not the auto position then the only difference is the switch position. The auto mode doesn't do anything to change the operation so if it doesn't do it then that means that the wiring and headlamps themselves are just fine.

If it were me, this would be enough for me to put the switch in it and go from there. Or just leave it in auto mode.

Let me know if you have questions. Thanks
