LED headlight & Fogs

[Black19]

I replaced the stock halogens with LED from underground lightning. The headlights (low beams only) are great. Bright, adjusted to not blind anyone. Great upgrade from stock. The fogs are the same with the exception on the drivers side. Seems to flicker and dim and then work great. Sent it back to underground lighting and Danny was amazing in checking it for over 8 hrs on the bench. He said the light is working no issues. While he had the light I swapped the fogs and the drivers side acted up the same way. Danny advised to try a anti flicker module or…..this is his email copied and pasted below.
“ We can try the anti flicker module. Its sounds like your oem plug is dropping voltage randomly. Which is not normal and i don't know why. If it's dropping to 9v the anti flicker should solve this. If it's below you need to find out why. Can be a bad ground or computer program the dealer would have to get involved. So with a halogen you won't see the power drop cause flicker it will go dimmer and will cause the bulbs to burn out fast.”
Has anyone had this issue? Not sure what to try next, the anti flicker module did not help.

Maybe there is an intermittent short in your wiring harness? Loose pin in a plug or worn insulation or something.

Sounds like a lot of voltmeter checking if you want to see where it's happening.

Agreed, does not sound like fun.

We had a set of Underground Lighting LEDs on one of our family Lone Stars and they were nothing but trouble with Danny telling me what to do.

They were a lot of trouble and we ended up dumping them for Lasfit which performed flawlessly.

We will never purchase Underground Lighting again…all one has to do is Google their address to see there are a UPS mailbox. Danny and his LEDs were a bust for us.

I hope your experience get better otherwise I’d return them to Danny for a full refund.

Swap the drivers and passenger side fog lights and see if the problem moves. Then you will at least know who to point the fickle finger of fate at.

I have already swapped and the problem stayed on the drivers side….checked for loose wires nothing found. Looks like a deeper dive into this is needed.
