Hyperflash On 2009 Ford Flex After Installing Trailer Wiring  

Question:

Purchased a Tow Ready T-one connector assembly for my Ford Flex and when connected to trailer the left blinker flashes too quickly like a bulb is burnt out. Bulb is fine. Not sure what is causing problem. I see you had a couple customers comment on similar issue. Any recommendations?

Expert Reply:

It sounds like you have a hyperflash condition with your 2009 Ford Flex. LED lights will flash like that because they do not provide enough power draw for the system to recognize them and the vehicle bulb-out sensor thinks there is a bulb out on the circuit.

You should start by reinstalling the T-One to make certain all connections are seated properly and not causing the problem.

If all of the connections are good and you have LED lights on your trailer, you may need Diamond LED Light Bulb Load-Resistors # DI34ZR to prevent hyperflashing of the blinkers.

I have attached installation instructions you can check out.
