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!)
