These superbright LED headlight bulbs are a H4 fitting and are a direct replacement for my son’s old Honda civic EP3. He loves the car and wanted a practical easy upgrade to the lights as one of the old halogen bulbs had died. They were very easy to fit taking about 3 minutes in total, the bulbs themselves look great and have a premium weight and feel to them. Once installed you can see the difference right away. They are so much brighter than standard, it’s quite surprising, and it makes driving at night where we live in the countryside a lot easier. I’m delighted so far with their performance and in my opinion they are fairly priced and are a simple fit. I hope you find my experiences helpful. Read more

In this LED H4 headla.p bulb kit you get a pair of LED replacement bulbs plus instructions. Additional information can be found on the website by scanning the QR code on the box. The H4 headlamp bulb has the dip and main beam in one bulb, plus a three pin connection. These are easy to fit, although vehicle manufacturer fitting vary most are secured with a spring clip. Disconnect the wiring connector to the old bulb, undo the clip and remove the old bulb. Remove the fitting plate from the LED bulb and fit into the headlamp and secure the spring clip. Then simply push the LED bulb in and twist 45 degrees clockwise to the stop, connect the wiring connector. Repeat for the other side and test. I found these LED bulbs much brighter than the originals with extended night vision. Good quality bulbs, highly recommended. Read more

I upgraded the old H4 halogen headlights on my truck with this NIGHTEYE LED kit, and it has completely modernized the vehicle's nighttime performance. The improvement is massive. The "5-minute install" is accurate; these are plug-and-play and fit directly into the H4 socket just like the old bulbs. The light they produce is a very bright, 6500K cool white, which is a huge step up from the dim yellow halogen light. It makes seeing the road and any potential hazards much easier. Since H4 is a dual-beam bulb, the most important thing was how it handled both low and high beams. The performance is fantastic. The low beam has a sharp, clean cutoff that illuminates the road perfectly without blinding oncoming traffic. When you switch to the high beams, the road is flooded with a powerful, far-reaching light. Both modes are uniform with no dark spots. For a simple, drop-in replacement that dramatically improves both your low and high beams, this kit is an outstanding choice. Read more

I was surprised at the excellent build quality of these headlamps considering the very competitive price. They're significantly brighter than the halogen bulbs they are intended to replace. It seems to be constructed with plenty of metal and premium components, including LED driver circuitry within the bulb itself rather than in an external control box as usually seen, and a built in heat sink - advised to consider clearance behind the bulb when installing to make the best use of this feature, and ensure no cables etc would jam the fan at the rear. The product description seems to be missing the operating voltage range - it would be good for customers to know if it would be suitable for trucks and lorries as well which often use a 24v battery configuration.
