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.

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.
