Highly Recommend *by E***D on Reviewed in the United States on October 6, 2018* The media could not be loaded.  10/10 I really like this LED backup lights ### ⭐⭐⭐⭐⭐ Nice Bright LED Lights. *by V***D on Reviewed in the United States on July 5, 2019* I tell you, it sure would be nice if car manufactures would just install LED lights in the first place; they are so much brighter than incandescent stock lights. It is just so hard to see things behind my car at night with the stock lights. Now I can really see so much better with these LED lights. I have no complaints about them. They were somewhat easy to install, had to remove some plastic out of the way, very carefully, find the old bulb, pull it out, install the new one, make sure it works because it has to be installed in the right configuration, once everything was back in place, I now had peace of mind. I will probably never have to replace these bulbs during the whole time that I own this car. ### ⭐ Could have been great, if they had worked at all. *by A***N on Reviewed in the United States on March 9, 2020* These were received promptly and in good condition, however regardless of them looking good, they did not work AT ALL.The review questions ask about ease of installation, well that depends on your vehicle, doesn't.Fortunately for me, these were bought to be used as daytime running light replacement lamps- not because mine had burnt out, but because I wanted brighter, more reliable LED bulbs.I installed them using dielectric grease as recommended, but they never ever worked at all and I ended up having to reinstall my previous bulbs, which as expected lit right up.Unfortunately due to a combination of the inclement winter weather, and some family medical issues, they couldn't be installed until 3/8/20, and by then Amazon's "liberal" return period of 30 days had expired. --- ## 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.th/products/74541854-marsauto-7443-7440-t20-led-reverse-backup-bulb-extremely-bright](https://www.desertcart.co.th/products/74541854-marsauto-7443-7440-t20-led-reverse-backup-bulb-extremely-bright) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
