Long story short, I replaced my HIDs that burnt out with another set.  In doing so, I also took my headlights off for the first time in order to drain the moisture that accumulated in them, and to seal them back up.  After reinstalling my HIDs, I noticed the beam pattern was different.  I have these shadows and jagged edges in the beam pattern that were never there before.  The light does not have a crisp line at all, and the light mostly focuses forward and doesn't have hardly any light down on the ground in front of the truck. 

 

Is there any sort of adjustment to the factory projector lenses that could be causing this?  From everything I've tried there isn't, and they seem to be working properly but I just can't understand where these jagged edges are coming from.  It is 100% not the lights as I troubleshot those to no end.

 

If there isn't any adjustment, are there different lenses that can be swapped into the factory headlights?  Really not trying to spend $900 on a whole new headlight setup.  Open to suggestions!

Have checked in dozens of times and messed with all of that.  Its nothing with the bulbs.  It SEEMS like it is, but I truly think something got knocked out of place in the projector lenses or something.  The light pattern is just really off.

Did you make sure nothing fell inside the projector housing and stuck to the inside of the lens like some tiny existing pieces of permaseal/dust/dirt? Highly unlikely but worth a shot.. Post some pictures when you get a chance.

 

There are multiple threads on here that swap 3" FX-R projectors and the cutoff line/output is far superior compared to stock. If I were to open mine up again I would either do this or the retro-quik kit from TRS. Cheaper option rather than buying a whole new assembly if all else fails.

Yeah I was looking at those recently.  I already have TRS HID's.  How hard are those projectors to swap out?  Any fabbing that needs to be done?

You just have to bake the headlights to soften up the permaseal, take the lenses off, and swap out the projectors. The retro-quik kit bolts right up to the existing 4 mounting points. Cutoff looks pretty dang good on these! Only downside is you'd need a D2S HID kit it looks like.

I did the retroquick system and found it easier to cut the rear of the housing apart and install the projector that way then seal it back up. Here’s my walkthrough.

Seems like a bit more work than I am interested in doing.  Might just keep running these and deal with it I guess.  Might upgrade the ballasts from 35w to 50w at some point.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
