16,000 lumens of ultra-bright illumination – eliminates halogen bulb inadequacy
- Insufficient headlight brightness at night
- Poor visibility on dark roads
- Halogen bulbs burning out frequently
- Heat buildup and premature failure
16,000 Lumens of Ultra‑Bright Clarity
Replace dim, failing halogens with precision‑engineered LED bulbs that turn night into day. See farther, react faster, and drive with real confidence.
Three reasons these bulbs outperform everything you have tried
16,000 lumens, no hot spots
A pair of chip‑on‑board arrays puts 8,000 lumens per side exactly where the parabolic reflector needs it — no scatter, no dark patches. It is a clean, EU‑passing beam pattern that stretches lane‑to‑lane.
Keeps its cool for 30,000 hours
A built‑in mute fan pulls air past 94 aluminium fins, dropping junction temp by 35 °C. The result is zero lumen fade during idle, and a rated life that outlasts your car’s bumper‑to‑bumper warranty.
High and low beam, in one bulb
Mechanical shielding inside the base keeps the low‑beam filament always lit, then adds the high‑beam circuit when you flash to pass — just like the OEM halogen you are replacing, but 300 % brighter.
Installation: five steps, no mechanic required
- 1Let the car sleep
Switch off the engine, disengage the bonnet, and wear clean gloves. Halogen bulbs run hot — give them 20 minutes to cool.
- 2Twist out the old bulb
Remove the dust cover, unclip the wire retainer, and pull the halogen straight back. Do not touch the new LED’s COB chips with bare skin.
- 3Seat the LED into the reflector
Align the three tabs. The LED’s base has a notch that mates with the housing — it only goes in one way. Press firmly until the retainer spring clicks.
- 4Tuck the driver module
The compact driver fits inside the headlight bucket. No external boxes, no drilling. Replace the dust cover — the IP68 connector seals itself.
- 5Power on and aim
Start the car, flick the lights to low beam. Park 7.5 meters from a wall and adjust the vertical cutoff to 1 % below the headlight centre line. That is OEM‑spec aim — zero glare.

From squinting at shadows to owning the road
The halogen bandwidth gap
At 60 mph, the 100‑foot halogen throw gave us 1.1 seconds of reaction time. Yellow‑washed potholes hid until we were on top of them. Every night drive felt like guesswork.
The 30‑millimeter miracle
Inside each compact housing, dual COB chips run at 80 watts combined, backed by a silent turbine fan and an aluminum substrate that wicks heat away 3× faster than copper. The result? A 6,000K pure white beam that throws 300 meters down the road without a flicker.
Highways become daylight
When you twist the key now, the road snaps into focus. Sharp cutoff, zero glare for oncoming traffic, and instant full brightness. From pitch‑black country lanes to fog‑soaked morning commutes, the headlights have become the most reassuring part of the drive.
Why a $60 LED pair beats a $40 halogen six‑pack
| This LED | Premium Halogen | |
|---|---|---|
| Lumens on low beam | 4,000 LM per bulb | 1,200 LM per bulb |
| Lifespan (hours) | 30,000 | 500 |
| Replacement cost over 5 years | $60 (once) | ~$150 (six pairs) |
| Startup delay | Instant | 0.5‑second warm‑up |
| Beam cutoff | Sharp, ECE‑compliant | Fuzzy, more glare |
| Power consumption (pair) | 80 W | 110 W |

Questions and answers
Yes, that is the combined output of both bulbs measured with an integrating sphere. Each bulb houses two high‑efficiency COB chips that draw 40 watts total, producing about 8,000 lumens per side. On a 12‑volt system, that equates to roughly 6,400 measurable lumens per bulb, which is four times a standard halogen. The 16,000 LM figure is real, not inflated.
The bulbs include an integrated decoder that mimics the resistance curve of a 55‑watt halogen. They work silently on 95 % of European, Asian, and American cars without throwing a warning. If your vehicle uses pulse‑width‑modulated lighting (some BMW, Mercedes, and Tesla models), we offer a free relay harness — just contact support.
The turbine spins at 5,500 rpm but uses a fluid‑dynamic bearing that produces less than 18 dB — quieter than the engine idle. In a garage with the engine off, you can hear a faint whoosh only if you put your ear 2 cm from the housing. Inside the car, it is inaudible.
A premium halogen pair costs about $25 and lasts about 500 hours, so in 30,000 hours you would buy 60 pairs — $1,500. One set of these LEDs costs a fraction of that, and you are done for the life of the car. Even at $60, the cost per hour is 0.2 cents versus 5 cents for halogen.
They fit any H4 / 9003 / HB2 socket, including most dual‑headlight motorcycles (BMW GS series, Honda CB, Yamaha FZ, etc.). The input is 12‑24 V DC, so they handle bike charging systems perfectly. The compact driver tucks inside the headlight bucket.
It is a pure 6,000K cool white — similar to factory LED DRLs on modern cars. It is not blue or purple. The colour temperature sits right where the human eye sees contrast best at night. It looks crisp and modern, not ricey.
