I need some help with led lights I bought some eagofar 8000 lumens led headlights manufacturer# S2D0012
they installed just fine no flickering but the won't go to low beam but when the truck is running they will 50% of the time this is my 2nd set of different led bulbs I'll add a pic any ideas??

 

I'd put the original halogens back into the light socket n see if they work as they should. If they do, then you know where the problem lies. If not, my guess would be in the column switch, main headlight switch or wiring in between..

 

Are they rotatable? Some you need to rotate to get the light to hit the reflector correctly. I believe the thin two sided ones work better than the ones you have.
