    I try to always let the data do the talking, it’s easier and more objective that way. I do again appreciate KC’s willingness to contribute the amber G4s to the thread.

    Also, you can always tell when someone has studied engineering/science when they refer to data in plural. :)

    If it's ok with KC, and if you have the time, any chance you can do the freezer test on the G4 fogs? It gets cold up here in Alaska after all, and since my SR didn't come with fog lights to start I'd need to get adapters or factory bezels regardless, so I'm torn between the G4's and the Rigid's SAE pods.

    The KC G4s will not preventing icing. Their strength is the highly efficient reflector based design, which allows them to utilize very low power. In a reflector design, a larger reflector is more efficient and more performant than a smaller one. If you look at the lens surface area the pods are approximately 9 sq/in while the G4s are over 12.5 sq/in. So the G4s have over 30% more surface area and less than 50% the power draw. Power draw is what generates the heat. Also keep in mind the heat is generated in the rear of the LED lights, and must radiate though the housing to the front. In short the KC G4 design is too efficient to generate enough heat needed to melt snow.

    Rigid SAE pods would be the only ones I would suggest in a regular snow environment, and not with amber covers. For excellent snow performance including a better color temperature for use in snow conditions, I would look at a halogen upgrade, which will provide more than enough IR (heat) to melt ice and clear the lens. This is what I run, as I cross windy 2 lane mountain pass highways in the winter, in the snow after dark more often than I would like.

    Installed the Rigid Fogs with amber covers after work today. I was deciding between KC and Rigid but ultimately chose the Rigid's because I can run the amber covers for bad weather and remove them to throw the most light downrange thanks to your excellent detailed analysis.

    Looks great! The versatility is certainly a benefit. I really like those cement grey trucks.

    Would you believe that cement was my 2nd choice? I was originally shopping for a quicksand one but my local dealer just happened to have the exact trim in manual with all the options I wanted in cement so I settled lol.

    I like quicksand too but I think cement is sportier and classier at the same time. 3rd gens have some great color options.

    Fancy looking. More efficient Amber filter? Excited to see more data. You do know you are empowering a small army of people to become lighting snobs. :hattip:

    What seems to be true about led lights is that they are bright to look at but not necessarily the best from the other side, where it counts.
    Would you think that hid are still in the ballgame?

    Off subject but there is a guy who painted his 80s yota pickup that cement color and man it looks sick. Much better on that truck than the 3rd gens IMO.

    Hmmmm I want to see this! Did you just put a yellow film on the stock lens? I like that better than the covers but the covers make switching so easy. Pros and cons to both I guess.

    My rigid DOT fogs are better than my Amazon special non dot pods I have for ditch lights. I am a converted lighting snob thanks to his threads. Good for knowing what to look for now bad for my wallet.

    I am updating my fogs in my 2017 offroad going with the KC G4's in amber, I want to give my stock fogs to a friend who has an SR5, does any one on here know if there is a wiring harness down there in an SR5 that you can easily add fogs to? He has all ready got my factory offroad wheels and tires, and grill!

    let me know what the data is and how it varys from the test you did with my pods and the cover! still haven’t even installed mine yet i’m waiting for my other headlight to show up. also my truck is at toyota for a month for frame replacement!

    I met with Rigid reps 6 months ago and purposed building an amber version of the SAE pod, along with some other ideas. This is their pre-production unit they are sending my way for evaluation.

    I completely agree on the color, way too blue for my liking, I was surprised just how high in color temp they are.
    Yes on both accounts. :) I should really finish my residential lighting thread, so people can be snobs about their home lighting too.

    The 80s and early 90s trucks are hard to beat and I could easily see that color looking sweet. Definitely some of my favorites.

    The SAE pods have 2 lenses. I had long thought about sandwiching some laminex inbetween them, but these are pre-production prototypes from Rigid.

    Buying quality the first time is cheaper in the long run!

    I’m unsure if the 3rd gens are pre-wired. I think I’ve seen threads on guys looking how to wire them so I don’t think so, but it would only take a minute to look under the truck at the back side of the fog location.

    Definitely what I was going to do!

    Yeah, the short wavelength light produced by automotive LEDs is very hard on the eyes when you are looking at the light source because of the way the light scatters inside your eye, making you think they are much brighter than they actually are. Which is why they seem so much brighter looking at them than they do from behind the wheel. It’s interesting how residential and commercial applications have solved this light quality issue, but it isn’t a priority for automotive.

    HIDs are still the leading producer in output by far. Even the putting the highest performing halogen into a 3rd gen is 2100 lumens, HIDs are 3200 lumens with much longer bulb life, though they do bring the added complexity of requiring ballasts.
