    It isn't as complicated as it sounds. Low beam bulbs and fog bulbs have a glare cap on the tip of the bulb to not provide glare from the high intensity filament to oncoming drivers. High beam bulbs do not have this feature, as glare isn't a concern in a high beam. An H9 is a very high output high beam bulb, so it has no glare cap. In a projector headlight there is a light shield to control the glare, and in most reflector low beam reflector headlights there is a bucket over the end of the bulb to control glare. A fog light is open without a bucket or any other method to cover the end of the bulb, relying on the blacktop glare cap coating on the end of the bulb to do so. An H9 being intended for high beam, does not have one. So I purchased some H9s that were modified with OEM style glare caps so the system operates like stock, but is massively brighter. The Rigid pods are just shy of 1000 actual lumens. My H9 fogs are 2100 lumens, I then push that output further by running a standalone 12 gauge wiring harness drawing power directly from the battery to increase voltage to the bulb for higher output.

    I tried to buy a set of the Volsas but no soup for me. I was wondering if you could just cerakote the end of a regular H9 bulb?

    Interesting, I've not heard of that product. What is important is adhesion and heat durability. I used high temp ceramic paint to put a cap on some 9011s. You can see my write-up here:
    https://www.tacomaworld.com/threads/the-h10-to-9011-hir-foglight-upgrade-better-than-led.528143/

    Note that any spray type paint will off gas as it cures, and off gassing in a sealed headlight will put a thin coating on your reflector/lens which will reduce performance. From what I have read, generally 90%+ of off gassing is done in 2 weeks. So if attempting this, I would spray, wait 2 weeks then install. I've found a company that actually sells the bulb cap coating material, but they they sold commercial volumes and my request for a 'consumer batch' went unanswered.

    Hey folks, I hate to be the bearer of bad news but it looks like the Amber G4s won't be available for @crashnburn80 to test for a couple more months. Long story short, our factory has been busy going full force on building stock of a different product. Therefore, the Gravity G4 production stalled out for the time being. We're trying to have it back in action ASAP, in huge part due to the overwhelming positive demand from you all on TW for these fog lights!

    Thanks for the update Taylor! I really appreciate KC's support and willingness to contribute the amber G4 lights to this thread, but Tacoma World just cannot wait that long. I've ordered the amber G4s from a vendor that has them in stock and they should arrive on Wednesday. I plan on updating the thread that evening. :)

    Thank you for the comprehensive and very technical review. I posted a question regarding fog light in FJ Cruiser group and got directed to this post. Definitely learned a ton and got a much better idea where to look.

    I saw that. Looking forward to see what they come out with as they make very nice lights.

    Never done, but always staying on top of it all. I have a good hunch I know what those are, but I'll double check with my connections and report back. :)

    Would these benefit from the upgraded harness?

    No. Upgraded harnesses are helpful to halogens to deliver increased voltage which makes a halogen burn brighter. LEDs have a much higher tolerance to voltage variances, and the G4s only use 10w compared to the 55w the circuit is designed for, meaning the OEM circuit is already overkill.

    Good question! As far as I know the G4s come only with the H11 connectors, @Taylor@KC HiLiTES could provide more information.

    So how do the KC Amber G4s stack up?

    YDgm18hxRAS7Z9Y3a5+Uyg.jpg

    dOsOoyVySKCbDOMxFgXzeA.jpg

    The KC Amber G4 produce an outstanding amber color, I measured the color temp at about 1800k. These are very amber fogs and should do excellent in poor weather conditions.

    Comparing to the 5000k KC G4s
    You can see the output of the Amber G4s does pay a penalty compared to the white G4s.

    4A44915B-B8C6-4A42-A87B-CC85ABDCA6C8.jpg

    In inclement weather you want to avoid short wavelength light which refracts very easily, causing you to see the snow/rain/fog in the air and not the roadway past it. Eliminating the short wavelength light greatly reduces that refraction off the precipitation so you are not illuminating the fog as the light isn't 'bouncing back at you' and instead illuminating the roadway beyond it. You can see in the spectrum comparison that while the amber lights put out less overall light than the white G4s, the short wavelength light has been eliminated from the spectrum for better poor weather performance.

    7117CB7E-3894-417B-817C-52CDE516B16C.jpg


    Of all the fogs in this thread, in my mind there are only two real contenders, KC and Rigid. Everything else compromises on reduced beam coverage and lower output. So how do the heavy weights of KC's true amber G4s compare with Rigids filtered lens amber pod?

    Rigid pod top (3070k) vs KC Fog bottom (1790k)
    FK9MIp%5Qx62N358ReBgFQ.jpg

    Pattern width. I checked horizontal throw, as this has come up as a hot topic. The KCs offer a wider throw pattern than Rigid.
    zVDTP99+S06ojnmyvFzkLA.jpg

    KC is far more amber vs Rigid's more yellow.
    xU8qfo+7SCKDG6vx%pkllw.jpg

    What does this mean for lux?
    Rigid 318 lux vs KC 127 lux.
    fullsizeoutput_db6.jpg

    Lots of info, what does it all mean? KC produces a better amber color light with a wider beam pattern meaning they should have superior performance in the worst foul weather conditions. However Rigid produces much more light overall though the beam pattern is narrower and the light color is yellower. Rigids higher light intensity and yellower color would be better for a multi-purpose light, providing improved performance over their white lights in fog but not matching KC's low amber color temp for extreme weather where you want to minimize refraction by using amber for best light 'penetration'.

    Awesome. BTW both real truck and CARid show them in stock as well. CARid doesn't have them, and real truck has been back pedaling for a week. Thanks for the update on summit. Getting a refund from realtruck and calling Summit first thing in the morning.
