So far, so good, when it comes to brightness, installation and quality.⚒️ InstallationThe installation is fairly easy. Cable management is a bit of a hassle, since I don't like to see cables. So I installed the main one it in the trunk (two of them), since there is a 12V plug and moved cables all around inside the panels and rubber seals. The length is NOT enough in that case, you need the extension cord as mentioned in the description of the product.? Durability of the housingDebatable, to be honest. It's heavy and the housing is made of some aluminium or metal, can't really say. But the durability seems to be great. However, I just own the product and have not driven around in summer yet, talking about heat here. Reading other reviews, the plastic casing of the LEDs itself is to be interesting how that'll hold in the heat.? Color and brightness of the LEDsThe brightness is just amazing. Not that you're blinding the opposing traffic, they are bright during day an night. I am not using tinted windows. In my case, I have selected the green color LEDs, and they are visible during clear weather, rain and even fog.? The rubber/cables are a bit softThe rubber casing for the cables are a bit soft rubber. Very flexible, but if you are not careful, you can easily tear them up. For example, if you have sharp nails or when the cable scratches too much across sharp surfaces. Electrical tape will do, but take care!? Price-wiseCompared to its competitors, I would say the price is fine. Not too much nor too less. But there are competitors out there with similar reviews and a bit lower pricing. On the other hand XRIDONSEN has the focus on LED strobe and emergency lights and that only. So I'm sure the service is a lot better than its competitors.⭐ OverallDefinitely a buy recommendation. The quality of the product so far, the brightness, visibility, the amount of options of flashing patterns and ease of installation and use makes it a recommendation from my side.
