F002H52012FT9 Iris Led Retrofit Head Light | HB4 Headlight | Elegant eco-friendly headlamp | Ready-to-fit | Halogen lighting with superior next generation technology

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.

Light is not bright at all, low quality

Installed these on my Next Gen Verna SX and this is such a huge upgrade over the halogen lamps! Verna's stock halogens are good for nothing. You can barely use them on highway trips. I had already upgraded from stock halogens to Osram Night Breaker Laser, yet these LEDs are a huge upgrade in terms of illumination. Pros: - Great build quality, not like el cheapo Chinese! - Great illumination - Low power draw - just 30W instead of 55W - Great spread for low beam: the low beam is good enough for most of the roads. I drove from Bangalore to Coimbatore after the upgrade with only the low beam for the most part and used high beams only when there was no other traffic. The difference between halogens is like day & night. - Instant full brightness - Straight fit into Verna's projector barrels - Driver is so small, that the connector and driver unit all can be stuffed inside the barrel - all it took was half an hour to replace the bulbs - Hope they don't fail soon :) Cons:- - High beam can be improved (the spread) a bit more Installation though did not take much time, was not a straightforward process with Verna Diesel. There is no space behind the headlamp assembly, to work. The assembly needed to be removed (for that need to pull the bumper assembly forward, for which need the tools...), to install the bulbs. The assembly cut-out and the dust cap position make it difficult to install because the fan unit has interference with the cutout and the dust cap locks. I had to remove some material on the bottom portion to properly fit the bulbs. The fan could be made a bit smaller, say if made of aluminium instead of plastic so that the installation could be much easier. Just because of this reduced by one star. Yet, this product is highly recommended.

Average Performance...Better than normal halogen

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.

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.

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.

Pictures are Bosch 35 Watts Led hi beam and low beam, Pictures are Halogen (OSRAM 12V 55/60 Watts) hi beam and low beam. Based on my experience I didn't find any difference in both Halogen and Bosch Led lights so don't purchase this bosch headlight Led's. Waste of money. Performance not so effective, Focuse not really better than Halogen, Appearance & Fit is okay, Warranty is out of question(not sure you can claim)
