What are GX Bi-Color LED headlight bulbs?

GX Bi-Color LED headlight bulbs are dual color LED bulbs that produce both 6500K cool white and 3000K golden yellow light in a single bulb, letting you switch between clear night visibility and strong fog penetration without changing bulbs. Each bulb uses 12 pcs of 6075CSP LED chips for a 360° beam, and each set outputs 110W and 25,000LM, around 650% brighter than halogen bulbs. Learn more about the full lineup in our GX LED headlight bulb series.

How do I switch between white and yellow light on GX Bi-Color bulbs?

Toggle your headlight or fog light switch off, then on again — the bulbs switch between 6500K white and 3000K golden yellow with each on-off-on toggle, no extra controller or wiring needed. The bulbs always start in white light every time they are powered on, because the switchback system has no memory function. This is the standard dual color switchback design used across the GX Bi-Color series.

When should I use the 3000K golden yellow light instead of white?

Use the 3000K golden yellow mode in fog, heavy rain, and snow: warm yellow light scatters less in water droplets than cool white light, so it reduces glare and backscatter and penetrates farther in severe weather. Keep 6500K white for clear nights and highway driving, where its higher contrast makes signs and lane lines easier to read. With one pair of switchback LED bulbs you can match the light color to the weather in seconds.

Can GX Bi-Color LED bulbs be used as fog lights?

Yes. GX Bi-Color bulbs are available in common fog light sockets such as H11/H9/H8 and 9006/HB4, and their 1:1 halogen-size body fits most stock fog housings. In fact, the 3000K golden yellow mode was designed with fog light use in mind — yellow light performs better than white light in fog, rain, and snow. Check your socket with our bulb size catalog before ordering.

Which bulb sizes does the GX Bi-Color series offer?

The GX Bi-Color series covers 7 common headlight and fog light sockets: H11/H9/H8, 9005/HB3/H10, 9006/HB4, 9012/HIR2, H7, H4, and H1, sold as a 2-pc set per socket. To find your size, use Select Your Vehicle and filter by year, make, and model, or email customer@auxbeam.com with your vehicle information and we will confirm the fitment for you.

Will GX Bi-Color LED bulbs trigger dashboard errors or flicker?

The built-in upgraded driver is CAN-Bus ready and compatible with 99% of vehicle computer systems without error codes. However, some sensitive models — such as Mercedes-Benz, BMW, Volvo, Dodge, Ford Fusion, Ford Focus, and Ford Escape — may flicker after installation. This is not a quality issue; adding a specific Canbus decoder resolves the flicker in these vehicles.

Do GX Bi-Color LED bulbs fit under my original dust cover?

The bulbs are mini sized at 1:1 halogen dimensions, but the built-in cooling fan adds extra length, so on some vehicles the original rubber dust cover cannot close fully after installation. The fix is simple and low cost: replace the stock cover with a silicone dust cap from our dust cover collection, which keeps the housing sealed against water and dust while leaving room for the fan.

How bright are GX Bi-Color bulbs compared to halogen bulbs?

Each set outputs 110W and 25,000 effective lumens, about 650% brighter than standard halogen bulbs, with a 360° beam pattern from 12 pcs of 6075CSP LED chips per bulb that removes the dark zones typical of cheap LED retrofits. The beam stays focused like a halogen filament position, so you gain brightness without blinding oncoming traffic when the bulbs are correctly adjusted.

How long do GX Bi-Color LED headlight bulbs last?

GX Bi-Color bulbs are rated for over 50,000 hours of use, supported by a dual copper heat pipe and a 12,000RPM cooling fan that exhaust heat through the aviation 6063 aluminum body. Efficient heat dissipation is what keeps LED chips from degrading early, so the bulbs stay bright for years of nightly driving. All non-clearance orders are also covered by a 2-year warranty.

Are GX Bi-Color LED headlight bulbs easy to install?

Yes — they are plug and play: the 1:1 mini body twists into most stock headlight and fog light housings like a halogen bulb, and the non-polarity plug means there is no wrong way to connect them. Most installations take under 20 minutes per side with basic hand tools. The only common extra step is swapping the dust cover for a silicone cap on some vehicles (see above), and our LED bulbs FAQ hub covers installation details for each socket type.

Reviews

The Auxbeam GX Bi-Color LED headlight bulbs are dual color LED headlight bulbs that combine 6500K cool white and 3000K golden yellow light in one bulb, switched by a simple on-off-on toggle of your light switch. Each bulb carries 12 pcs of 6075CSP LED chips to produce a 360° full beam with no dark spots, and each set outputs 110W and 25,000LM — around 650% brighter than halogen bulbs. The golden yellow mode cuts through fog, heavy rain, and snow far better than white light alone, which makes this series a practical upgrade for drivers who regularly face severe weather at night.

UPGRADED FEATURES

GX Bi-Color LED Headlight Bulbs

Each GX Bi-Color LED headlight bulb uses 12 pcs of 6075CSP LED chips (75 mil, larger than standard chips) to project a clear 360° beam pattern with no blind zone, so road signs, lane lines, and roadside objects stay visible from every angle.
A 110W, 25,000LM output per set delivers about 650% more brightness than halogen bulbs, giving you a noticeably wider and longer light beam on dark country roads without extra power draw from your vehicle.
The dual color design (6500K white + 3000K golden yellow) gives you two beams in one bulb: white for clear night visibility, and golden yellow for stronger penetration in fog, heavy rain, or snowfall — no need to swap bulbs when the weather changes.

SWITCHBACK FUNCTION: ONE BULB, TWO COLORS

The bulbs start in 6500K cool white by default. Toggle your headlight or fog light switch off and on again, and the bulbs switch to 3000K golden yellow — a true switchback LED headlight bulb function with no extra controller needed.
Golden yellow light (3000K) scatters less in water droplets than cool white light, so it reduces glare and backscatter in fog or rain and lets you see and be seen more clearly in bad weather.
White light is ideal for clear nights and highway driving, while yellow light suits fog, rain, and snow — both modes come from the same pair of bulbs.
Note: the bulbs always start in 6500K white light each time they are powered on; there is no memory function to resume the previous color.

PLUG & PLAY, MINI 1:1 SIZE

With a 1:1 mini size that matches halogen bulbs and a non-polarity plug, the GX Bi-Color bulbs install directly into most stock headlight housings — twist out the old bulb, twist in the new one, done.
Note: the built-in cooling fan takes extra space. If your original dust cover cannot close over the new bulb, replace it with a silicone dust cap — see our dust covers collection for compatible options.

50,000 HOURS LIFESPAN

A dual heat pipe design pulls heat away from the LED chips, and a 12,000RPM turbo cooling fan exhausts it through the aviation 6063 aluminum body — a 4X heat dissipation system that keeps the bulbs stable at 110W output.
Efficient cooling reduces bulb failure and supports a lifespan of over 50,000 hours, so most drivers can expect years of nightly use from one set.

BUILT-IN CAN-BUS READY

The upgraded driver system communicates with 99% of vehicle computer systems without triggering error codes or dashboard warnings.
A few sensitive vehicle brands (such as Mercedes-Benz, BMW, Volvo, Dodge, Ford Fusion, Ford Focus, and Ford Escape) may flicker after installation — this is not a quality issue, and a specific Canbus decoder solves it.

My $10 halogen bulbs are better

Sucks that I was hopeful on the yellow/white H7 led bulbs but they underwhelming under preform. I bought auxbeam in the past when they had cheap led light bars back in 2015 and liked them, they weren’t great they worked enough when I couldn’t afford good stuff. I’ve seen ads for the combo headlights and thought they would be great for my dually since I tow and they were advertised to be bright and cast a distance away. Well these suck, at least in my application they are terrible. I wasted money on new headlights so I can use these and it was a giant waste of money. The cheap stock halogen bulbs that came in the lights have better throw and brightness than these. I wish I could return them but they had some stupid hourglass shape for no reason and I had to file the wings a little to get them to fit.

Gx series bi-color

Good lighting both white and yellow. And good customer service. Moreover, I had a issue and they solve it right away.

terrible service

I ordered these lights for my truck. They were not complete when I received my order. I tried to call the company and have a discussion with somebody that knew what was going on and had no luck. They couldn’t take my call and they were communicating to email at 1,2,3,in the morning. horrible experience sent the lights back for a full refund. Be lucky to see that good luck everyone

very well made

the bi color bulbs work very well in foggy rainy conditions however they dont seem to have HI beams in yellow.
