Only what is directly I front of my truck seems to get illuminated in the slightest. Anything to the left or right gets no light at all it seems. I have to roll my window down and stick my head out when navigating dark parking lots or any tight turns at night.

I wonder if hids would even make it better without switching out the lenses

 

just ordered these
GMC Sierra Morimoto Elite HID System - HID Systems from The Retrofit Source Inc

hopefully it helps

 

I have HID's in mine and they are great. On high beam it's like I have spot lights on.

 

what HIDs did you go with? no issues with the bulb hitting the flapper or melting **** i guess?

 

Nope. Mine are Xenon Supply, I had the kit on my car and just got the different bulbs and moved it over to my truck. I always use a stand alone harness also.

 

Pat is that in the 2014 you upgraded to HID?

 

So I purchased the trs sierra spec kit and I'm trying to wrap up the install. The passenger side is not coming on, it flickers one then turns off. I tried flipping the capacitor every way possible but results are the same. Driver side works like a champ. Hoping to get this worked out before I go to work in the morning.

Driver side works perfect. left the factory plug un connected



Passenger side, factory plug plugged into the bulb harness (red to red), bulb harness plugged into the capacitor harness section, capacitor section plugged into the harness from the relays.

 

Yes it is.

 

There is a gm tsb out for poor headlight performance. The dealer will replace the bulbs with a better product and reflash the bcm to send a stronger frequency voltage signal to the bulbs. I haven't seen it in person yet, but people that have had it done say it's a 100% improvement

 

^ thanks for the info man.
