    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.

    Good light, but blinding
    Size: H7
    The light itself is good and bright and fits well, but I don't know if I installed it wrong, but the driver's side is very blinding, and I feel bad for other drivers and can't do anything about it.

    Easy to install, extremely crisp and bright
    Size: H7
    My H7 Termitor Headlights are wonderful for my 2014 VW Jetta SE 1.8l turbo. Extremely bright and super easy to install since they have the exact fitting as the factory bulbs. Only thing I would have done differently is to use the adapter to maintain steady light. Whenever I'm in gear or roll the windows up or down I can see the lights dim and after I drive for a while they aren't as bright as when I first started the car. Otherwise they are great, very bright, no warm up time, and clean crisp light. They're even brighter than my factory brights (which I still have installed with the factory bulbs, can't even tell they're on with these!)
