High beam upgrade for 2016 High Country 2500HD?

I'm just getting back from up north and the high beams in this new truck won't cut it in moose country. The high beam throw is too short and too low. I'm looking for a simple plug and play solution to this issue. I'd apprectate your suggestions.

"simple" and "solution" usually aren't used in the same sentence.

However, a few things that may help based on my experience with my 2015 Denali. Which does have different headlights, a single projector. But it likely has a few things in common.
First, GM like most everyone else doesn't use very large wire going to the headlights, and has a fairly long run. And light output is very very very strongly depedent on voltage. it is FAR from a linear function. So, assuming they are not HID, but a regular halogen bulb, rewiring so that you use a relay to power a short run of #12 directly from the battery to the bulbs and a short run to ground with #12 you will pick up somewhere between 0.5 and 1.0 volts to the bulb. That may not sound like much but it is very very noticable.

Now, most of the light pattern is dictated by the reflector, which isn't easily modified.

If the truck already uses a HIR bulb, there is a HIR+ with more light output and shorter life available. That also helps. If they are using a normal 9005/6 etc. a change to HIR bulbs will make a noticeable improvement.

IMHO stay away from the Silverstar bulbs. yes they are somewhat brighter, but the life is terrible. Sylvania admits it and has sent me free replacements untill I gave up on them.

I have had to aim the HIDs on my 2016 Chev LTZ. Nothing new... I have had to re aim every vehicle I have ever owned.
They were aimed in the ground about a 100 feet out ahead of the truck, box empty.
The book says 2 1/2 inches down at 25 feet. I aimed them up to about 1 inch down at 25 feet. Works a whole lot better.
The book does detail how to adjust the headlites. One screw on each side adjusts both high & low beam. To adjust individually is more challenging.
I do keep the screw driver with me, for when I drop a trailer on the hook.

Does this have a bearing on your high beam issue.

I hope it doesn't come to this, but I will look at what's involved in aiming just the high beams.

Thanks for the reply. I'm pretty sure the high beams are just 9005 lamps. I've read about using trimmed HIR 9011 lamps. I'm not sure what an HIR+ is, unless you are referring to the original Toshiba HIR lamps. It's my understanding that these haven't been made for some time.

Just curious..... does yours have four headlites? Two HIDs that act as low/high beam, and two below those that act as highbeams only?

I do find that the high beam lights seem to be a bit yellow. The lows are white for where they are aimed. As said, aiming is needed. The highs/floods are not a good as my 05.
