Review on Auxbeam 9007 LED Light Bulbs, 9007 HB5 LED Light Bulbs 50W 5000lm Dual Beam Bulbs, Ultra Bright 6000K XHP70 Chips 9007 LED Conversion Kit F-16 Series by Doug Small

I've only used them for about an hour, but I can give some feedback on them.1. Assembly. Not as easy as one might expect. I installed them but due to the design if your car has tight tolerances then fitting can be tricky. I had a hard time hooking them up. Also, they are very easy to connect in terms of connectors etc. 2. Brightness. What an improvement over halogen. Unfortunately, after the installation, I got into thick fog with my truck. You did very well. The high beam isn't much bigger than the low beam, but since the low beam already shines so well, it hardly matters.3. Longevity. I can not say. I've only had them running for an hour. General disadvantages: 1. Installation instructions. Very weak. There's no mention of having to install screwdrivers, and while they have detailed pictures, they still suck. Chinglish numbers are small, which is surprising. You can understand what they have pretty well.2. Warranty. They talk about their 2 year warranty and scam you but when you read the exceptions it's pretty bad. You can have many ways to reject warranty claims. For example, let's say your lightbulbs stop working within two years. They have one exception where they do not guarantee defective LEDs. You can also exclude claims for "installation problems", tight housing space or incorrect installation position, etc. So you left yourself many loopholes to not comply with warranty requirements.3. Returns. They will send you an RMA label etc but on the website it looks like you need to ship them back to China. So if they're paying for shipping, great, but you'll have to wait quite a while so don't expect a new set any time soon if they're warranty compliant.
