Plug-and-play full LED headlight for the Ninja 400 — 300% brighter than stock, with an RGB DRL you can actually see at night.
WHY RIDERS SWAP THE STOCK UNIT
- 300% brighter output. Dual LED low beam + dual LED high beam. Road signs, lane markings and deer eyes reflect back at you long before the stock halogen would pick them up.
- RGB DRL with integrated turn signal. Seven selectable colors on the daytime running light bar, with the turn signal built into the same fiber-optic strip — no extra indicators bolted to the fairing.
- True plug and play. Bolts into the OEM housing using the factory mounts and connects to the factory harness. No cutting, no drilling, no relay splicing. Roughly one hour with basic hand tools.
- Built for weather. Sealed housing rated 【IP67】, polycarbonate lens with UV coating so it doesn't yellow after two summers.
- No CAN-bus errors, no flicker. The included driver is matched to the Ninja 400's electrical system, so the dash stays clean.
- 1-year warranty, no return shipping. If a unit fails inside 12 months, we ship a replacement — you don't send the defective part back.

WARRANTY & SUPPORT
Every KT headlight carries a 1-year warranty. If something fails, send us a photo or a short video — we ship the replacement. Within the first 3 months we cover shipping; after that, shipping is on the buyer, and the part itself is still free. We don't ask you to ship the defective unit back.
FAQ
- Will this fit my 2024 Ninja 400? There is no 2024 Ninja 400 in the US, EU or India — it was replaced by the Ninja 500, which uses a different headlight. If you're in a market where the 400 is still sold (e.g. Japan), 2024-2025 units fit.
- Do I need to remove the fairings? Only the side panels and the two upper bolts. No full teardown.
- Will it throw an error code? No. The included driver is matched to the bike's electrical system.
- Is it street legal? This assembly is intended for off-road and closed-course competition use. Check your local regulations before using it on public roads.
- Can I keep the factory turn signals? Yes — or use the integrated ones in the DRL strip and remove the stock stalks.
Troubleshooting Before a Return
1. If you experience a problem with one of our products, we strongly recommend troubleshooting the headlight first.
2. We would like to believe that every light we build is perfect - and that is certainly KT's goal. In fact, the vast majority of our headlights are still in the field doing exactly what they are supposed to do. But even with our high quality standards, occasional problems can happen. We stand behind our products, and if you have an issue, we will make it right.
3. However, we do receive some returns where the lights are tested and found to work exactly as intended. That means wasted time, effort, and money for everyone. Before returning a product, please go through the simple checks below - they will help you determine whether the issue is covered under warranty.
4. If the cause of the problem is unclear, please first perform a bench test: remove the headlight from the motorcycle and connect it to a separate 12V power supply. If the headlight functions properly outside the motorcycle, the problem lies elsewhere on the bike, and a return for that reason would not be covered under warranty. Not sure how to judge? Contact us first - we have a video channel with troubleshooting guides for all our products.
One-Year Warranty
All KT headlight assemblies come with a one-year warranty. If a defect or malfunction is found and verified during the warranty period, KT will provide free replacement part(s). Considering the high international shipping cost and customs taxes, KT will not ask you to send the defective parts back.
For verification, we only need pictures or a short video showing the defect or malfunction:
1. Within 3 months of delivery: KT covers the shipping cost of the replacement(s).
2. From 3 to 12 months: replacement parts are free; the shipping cost is covered by the customer.
3. After 1 year: replacement parts are still available at a reasonable price.
