My old mechanic installed LED headlights on this vehicle listed above Truck Mountaineer, 4.0L FI SOHC. But it has the check headlamp error now and check high beam. Do I need some type of load resistor? What kind would be the easiest and best to install?

Hi,

The LED lights draw very little voltage. As a result, the vehicle thinks the bulbs are burned out. LOL

As far as a resister, yes, it is needed. I attached a picture below of what I would suggest. Please understand, we can't make recommendations on parts. However, I feel this would work for you. I believe this vehicle uses a 9005 bulb. Please confirm that.

Take a look at the picture below from Amazon. Also, neither 2carpros nor I have anything to do with Amazon. I don't want you to think I'm recommending this for kick back. LOL

Take care and let me know if this helps.

Joe
