Bosch H4 iRis

I upgraded to the Bosch IRIS LED HB4 retrofit headlight, and I’m really impressed with the performance! The light output is much brighter and clearer than standard halogen bulbs, giving me much better visibility on night drives. The beam is crisp and focused — no more struggling to see road edges or signs in the dark.

The light output is good and installation is easy. The price is also reasonable. Its rated 30 watts which is sufficient for high beams and do not strain the wiring and couplers. Only problem I faced one of the coupler had a loose connection issue.

Recently upgraded my high beams to the Bosch Iris HB3 9005 LEDs for my Corolla Altis, and the results have been excellent especially considering my car uses a reflector-based headlight setup and not projectors. The brightness improvement is immediately noticeable. Light throw is strong and clean, and long-distance visibility has improved significantly, making highway night driving much safer and more confident. The beam pattern is surprisingly controlled for a reflector housing no scattered glare, no patchy hotspots, and the illumination remains focused where it should be. The color temperature looks crisp, modern and gives the car a premium look without being overly harsh on the eyes. Heat management also seems well-optimized; even on longer runs the driver did warm up a bit as expected, but nothing concerning or unstable. No flickering, no sudden cutoff extremely stable output. Overall, Bosch has done a great job with this LED. For anyone with an HB3/9005 reflector setup wanting better visibility without switching to projectors, this is a genuinely worthwhile upgrade. Definitely happy with my purchase.

One Bulb is bright and other is dim ( low brightness ) also use in another vehicle same problem with product pls find video and upper dipper not work in it.

Finally LED Headlight From Reputed Manufacturer which doesn't Suck. Each Bulb has high-quality build and they perform better compared to halogen bulbs while using nearly half of the wattage. Low Beam is Spread is amazing and can drive without the need for fog lights. The intensity of the high beams is amazing. Instead of buying Philips Ultinon PRO 9000 HB3/9005 which costs nearly double of this and improvements are marginal this is best upgrade. I am using these in Hyundai Elite i20 with Bi-Halogen Projectors.

Original LED bulb brightness good

I put these lamps in a Tiago’s low beams(halogen projector) with Iris LED H11 The light distribution is very uniform and there is significant improvement in light output. Cost is high in my opinion, and longevity - need to see. So far very happy with results(had a small concern if led lamps will mess up the beam pattern, but no issues)

They didn’t highlight the fact that this lights has only 60wattage(30w/light) which won’t be enough.And As per the price point these are worse.Save your money and go for other reputable brands like Osram which offers 50-80w led lights.
