I don’t typically give 5 stars but these bulbs deserve the rating.
Vehicle 2017 Kenworth T-680
Low beam (Projector style) H-11 bulb
High Beam (Reflector style) 9005
I have been running Seagate LED bulbs in the low beam for over a year and they have worked flawlessly while providing a lot more light than the Sylvania halogens that they replaced. Since new H-11’s were included in this order I changed my old LED’s and I was surprised by the additional power. A very clean bluish white light, true 6000K. My real amazement came from the replacement of the Sylvania Halogen bulbs that I still had for my high beams. (I had retained the halogen bulbs on the high beams because they heat the lenses better during cold weather, frost Ice and snow accumulation melts using halogen bulbs). Replacing the high beams was a literal difference between night and day though and while I may switch back to Halogen for winter, as changing them was a 2 minute job for all 4 bulbs, for now I can’t imagine needing any more light than these bulbs provided.
I have one concern about the longevity of these bulbs as they use a fan to cool the heat sink, but only time will tell if it’s a legitimate concern.
The pictures that I provided were taken while driving on I-25 with a pitch black night (no city lights, no moon, heavy cloud cover), 1st picture is using High beams with the second picture being only low beams.
