Fog light adjustment screw

GMC-AT · January 30, 2014

I changed the fog lights to VLEDs. They look much better and I brighter. Anyway.. I noticed when I was changing the bulbs, there was an adjustment screw. I didn't mess with this and just replaced the bulbs and hooked back up.

Well tonight I tested out the lights. The beam seems high. Can someone tell me.. does that adjustment screw control right to left? Or up and down ?

It controls up and down. Their is no adjustment for side to side.

Have any of you guys had to adjust after installing new bulbs? It seems to me a little too high, but it may just be the new light is much brighter

It's b/c stock functions like spot light and LED like a flood, therefore you now have more light above the bumper. Pics & explanation in the LED fog topic here: http://www.gm-trucks.com/forums/topic/156170-led-fog-lights/page-9

That does make sense, I noticed the light was much more like a flood, wider bigger pattern

Has anyone put these in the low beam headlights. If so, how would you rate the improvements. Also what size is the non projector low beam for the Silverado. Thanks.
