I have a new to me 2017 F350 6.7 Platinum CCLB. The DRL lights are not working correctly. I have a bright spot in a small portion of the driver headlamp. The rest of this DRL and the passenger DRL are dim. Is this repairable or do I need new headlight assemblies? I have seen some aftermarket DRL replacements that require opening the headlight, are these worth of ****?
