I have a fair bit of LED bulb experience, however haven't gotten around to trying some in the LS head lamp assemblies. I have some spare (both GEN's) head lamps down in the basement for such experiments at a later time.
However ... allow me to comment on LED Bulbs in general.
Over the past, I'd say, year and half, I've been purchasing many of different brand LED bulbs for my work truck, a 2016 Peterbilt 579 full condo sleeper. Primarily because I do a lot of night driving and clock anywhere from 1000 to 1200kms per shift. 5 days puts me in around 5150kms (3200mi) each week. (give or take, give the directions of my loads).
Regardless ... for the most part, I drive at night and the original stock halogen 9005 & H11 bulbs were too yellowish and weak. Little to no range and was tough to spot the wildlife. ( I deal with a lot of Moose running out West Canada and back in the deep secluded woods along Hwy 17 Lake Superior ).
It's tough to spot these large monsters in the dark with simple weak Halogen bulbs and last thing I need is to bounce off the rocks or into the ravines over the edge and kill myself. I had to do something and we are not allowed to drill holes anywhere to install LED light bars, so I had to opt for just upgrading the Bulbs.
Small collections of bulbs I had been experimenting with.
In my Peterbilt work truck I settled on,
9005 High's = ATSHARK, 100W @ 8000Lms in 6000K output.
That's 50W @ 4000Lms per bulb.
H11 Low's = ATSHARK, 80W @ 7200Lms in 6000K output.
That's 40W @ 3600Lms per bulb.
THEY ARE STUPID BRIGHT WHITE LIGHT !!!!
I had tried several other brands and variations of outputs but it just wasn't going to get any better.
It's difficult to determine if the next bulb is better then the last.
It comes down to such a small fraction of a difference I simply couldn't tell if it was brighter or not.
I eventually stopped spending more money and settle on what I had, I put the same set in my 2009 Silverado. Although they do fit, I had to remove the whole lamp assembly, insert the bulbs, ensure the polarity then remount the lamps.
They are so tight, the back end of the bulb/cooling fan is near touching a cross member within a few millimeters.
STUPID BRIGHT WHITE light at 6000K output.
Thing to watch out for with all these LED bulbs for sale on both eBay and Amazon is that there are many vendors or sellers that are doing Private Labeling from China. If you look close enough at all the ads, you'll possible note that they are the same bulbs but with different packaging and name branding.
I also found that after 40W 3600Lms @ 6000K white output per bulb, they are all the same. Such a small difference it's barely noticeable or even any better/worse.
I picked up a cheap set that promoted in the ad that they were 100W's a set, meaning 50W bulb per side but they were cheap Private Labeled brand and total garbage. For one, it was slightly less bright then my best set and second, one bulb, the fan would shut down after about a minute and thus turned the bulb off due to excessive heat. Some sort of thermo problem. I managed to get my money back on those on a return. I claimed they were false advertising and simply defective out of the box.
I've also picked up a set, although good output and clean spread, they fans' are very noisy compared to other Bulbs I had tried. Not a huge deal, good output was more important than fan noise which you'd not really notice once the hood is closed and going down the road.
It's tough to do a recommendation of brand names, there are a couple good big brand name LED bulbs available but I can not understand why they'd want 100 to 150$ a set when the average pricing all over Amazon is somewhere between 50 to 80$.
I just settled for what I had already purchased, it wasn't going to get any brighter.
You'll want to watch the size of the cooling fans on the back end of the LED bulbs, you'll need the room to keep them inside dust covers or lamp assemblies.
My 2009 Silverado, the bulb just simply protrudes past the lamp housing. My 2016 Peterbilt work truck, it's all contained within the housing and accessible via a large round dust cover. I ended up putting a set of 9003 Hi/Lo in my Polaris XC800 Edge Sled also. Had a retaining clip to keep them in place, works just as intended and is simply STUPID BRIGHT WHITE light in front of me when out ripping around in the farmers fields or trails.
I don't have any 'still' pics of bulbs installed, I do have some sample dashcam videos I could share.
