Wtf is going on with these headlights. First they flickered. Ive taken the whole dash off looking for shorts. I resolved that issue(loose ground under hood). Go figure.
Since I bough this truck Ive had ZERO low beams. I have LED "truck lite" front lamps installed. High beams work great. "Useless"
The low beams do absolutely nothing while the truck is running. If the truck off and turn on lights(low) they come on....... Start the truck and they disappear. If I leave the lows on with the truck off, the headlamp delay buzzes. Once the delay stops buzzing the lows turn off.

Could the delay be the issue?

Is it possible the the lows ain't pulling enough juice to keep the relay open because there LED?

 

here ya go

 

I want to make sure I'm understanding this..Did you have low beams before installing the LED headlights?

 

I inherited the problem. They were already installed when I bough the truck. Im thinking of just installing a new harness. He said they were plug and play. And If that doesn't fix it, it must be the delay module..

 

What happens if you install a sealed beam headlight?

 

Im not sure. Need to see if I have some old lights laying around.

 

Yes that's what I was thinking. Try swapping the LEDs for some regular headlights. If the low beans start working or still don't work we'll have an idea which way to go. The H6054 headlight is used in countless vehicles so it should be easy to find working ones to try out

 

Fixed them. I still need an anit-flicker decoder. Gonna upgrade that harness too. I already ordered it.

 

Problem solved..
