I would highly recommend replacing both at the same time so you have equal lights and brightness. at the back of the lamp, it has small fans that are activated when you turn the lights on. I have replaced my old halogen bulbs which one had blown. I can confirm that these project slightly further but also the distance seems to be lit up more instead of a small area.they were easy to replace but screowing them into the fitting and plugging into the female plug on the car. ### ⭐⭐⭐⭐⭐ Big! *by J***E on Reviewed in the United Kingdom 🇬🇧 on 2 December 2018* Arrived promptly. They are great. One thing I didn't expect (but it's fairly clearly pointed out): these are BIG compared to normal bulbs. Distance from notch to tip is the same, so they'll fit in any H7 lens, but there is a big heatsink and fan hanging off the back. If your bulbs have a wire clip or not much clearance before the dust cap, they may not fit. They didn't in my Rover 75. I just took the clips off, and they're now held in place with the dust caps. They may jolt free (much heavier than regular bulbs), or they may overheat due to lack of ventilation -- if they do either I'll update this review. If I don't update the review, it's because they were fine. I do 70 miles a day, so if anything is going to happen, it'll probably happen soon.EDIT:Removing the clips caused the car to fail the MOT, which was a huge pain, because getting the clips back in to pass it meant disassembling the front end. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/88752912-hsun-h4-9003-led-headlight-bulb-all-in-one-conversion](https://www.desertcart.co.uk/products/88752912-hsun-h4-9003-led-headlight-bulb-all-in-one-conversion) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-30*
