Why do my headlights turn on off and on again when I remote start the vehicle

It only happens when I use the remote start. The automatic lights turn on, off, on, off and on again. I have the t harness.

Did you connect parking lights?

Is your vehicle equipped with auto lights? If so what position do you leave the parking light switch in?

Yes my vehicle is equipped with auto lights and I keep them on the auto setting.
Does the symptom change if you switch the auto lights to the OFF posiion?
It’s does the same thing
My colleague Derek had  asked if you had connected the parking lights from the Evo to the vehicle. if yes, how and where was it done?
I connected the parking light wire (green/grey) to the BCM white 26 pin connector and put it on pin 22 using the splice connector that was provided.
I followed the directions as stated in the installation guide.
Which wire on the Evo did you use? And how did you test the parking light wire you connected to?

Our units do not come with splice connectors, where and who was this unit purchased from?


Thank you,
How do you test the parking light wire once you connect it. I ordered the unit from Amazon
You're supposed to test the wire before you connect to it. This is the proper and safe way of installing in a vehicle.

Please disconnect the wire and test to see if the issue with the lights go away.

A digital voltmeter or logic probe should be used for testing.

May or may not be related but a lot vehicles when they crank the lights turn on-off-on. Start your car with the key to see how they react.

When I start my vehicle by putting the key into the ignition and start it the lights are fine. It only happens when I remote start the vehicle. :/
Was there any resolution on this? Mine is doing the same thing. 2016 Ram 1500 Evo All remote start
