This sorted the problem instantly. ### ⭐⭐ 2.0 out of 5 stars Did not stop flickering *by B***R on Reviewed in the United Kingdom on 4 May 2023* Solved the can bus errors but the lights flicker for the first 15 seconds after they are switched on. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars LED headlight flicker on 2006 Jeep Grand Cherokee fixed with this device! *by J***S on Reviewed in the United Kingdom on 11 January 2022* I had purchased Bevinsee LED headlight bulbs for my 2006 Jeep Grand Cherokee Overland. The high beam headlight would not fully turn off when switched to low beam lights and would flicker. This device fixed the problem. Installation was simple as was just a matter of installing this between the headlamp connector and vehicle headlamp harness. You have to pay attention to polarity. Works great. Item feels like it is robust and well made. If you have a flicker problem with aftermarket LED bulbs, this seems to fix the problem, I can confirm it works at least for a 2006 Jeep Grand Cherokee. --- ## 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.com.kw/products/91600521-koomtoom-h4-9003-led-load-resistive-connectors-led-bulbs-anti](https://www.desertcart.com.kw/products/91600521-koomtoom-h4-9003-led-load-resistive-connectors-led-bulbs-anti) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
