These are quality bulbs and more reliable than halogen
Size: H7
Car that I drive is a 2008 Mazda 3 4Dr Sedan Automatic i Touring. Got so tired and fed up with felt like spending money every month or so on halogen bulbs. It was always the same old story, trip to auto zone to avoid a fix it ticket. I almost tried to buy the Sylvania brand on Amazon for cheaper but what's the use? Its STILL the SAME product. I'm done with those and never going back. The new Territory Has snapped right in without any special add on adapters, just plug and play deal. Way brighter and super easy. Love them. Can see way better at night and not have to worry about them burning out so quickly anymore. More than I can say about the Sylvania brand "Made in Germany". They're slippin

I’m really happy with these lights! They were easy to set up, work perfectly, and give off a beautiful glow. The brightness is just right for creating a cozy and relaxing atmosphere without being too harsh. The quality feels great for the price, and they instantly made my space look more modern and inviting.
I also appreciated how well they were packaged and how quickly they arrived. Definitely worth the purchase, and I would absolutely buy them again. Highly recommend to anyone looking for stylish and reliable lights!

Termitor H11 are so worth it
Size: H11+9005
LED Lights are as described. They fit perfect in the low beams and high beam spots. LEDs are super bright and work great at night! Soo much better than the old fluorescent bulbs that came with my rig.

Bright light
Size: 9004/HB1, Size: 9004/HB1
Keeping track of longevity. Had these bulbs for a month and will try and update if they fail. Unfortunately a while ago I hit a cow, seemed to just pop up out of nowhere, the truck was rebuilt and I wanted more/better road lighting. I am using these in a Mack truck for work so they are getting used. I run at least 10 hours a day, 5+ days a week and have at least 11k miles on them since installed. Install is just like a standard bulb no special steps needed. Produce a lot of light and good patterns on high and low beam. So far I really have only had one issue with the bulbs and that is the daylight running light/DRL operation, they don't work I believe the Mack drops the voltage to slightly dim the lights when running in DRL operation and this causes the bulbs to just intermittently flash so I just run with them on all the time. This I don't believe is the bulbs fault and is more an analog vs digital issue. Therefore I'm testing the longevity of the bulbs if my truck is running they are on. Will see how they do as the days get hotter as they are in a small sealed space.

Wow bright!
Size: H11+9005, Size: H11+9005
I have used Fahren LED headlights in two of my other vehicles so I had a baseline of what to expect, but these upgraded ones are even brighter than the ones in my other two cars. I love this brand because they are plug and Play so I have not experienced any compatibility issues. These feel high quality as I have expected due to past experience with this brand. I much prefer the bright white color of LED versus the yellowish Amber of halogens. I have been using this brand for several years now so I expect a good lifespan from this as I have experienced from other bulbs from this manufacturer. As far as value goes, the increase in visibility installing these is worth every penny and then some.
