These work great for what they are, I had the beamtech fanless h11 installed and they were just slightly brighter at similar price. Installation was ok. I had to adjust the h11 socket collar to accomodate my housing. I had to drill a new hole on the h11 collar to have the LEDs facing 90° and 270° degrees aka east and west on the housing to properly focus the bulb, once that was attained focus beam was identical to the halogen H11. I will update with photos of this change-point. Color is a crisp amber yellow, great addition to the 5500k morimoto HIDs. Been running the Auxito H11 amber fog light bulbs for a week now with no issues on my daily driver. Longetivity we will just have to wait to find out. For 29 bucks im not complaining. Is this bulb a good addition to your setup? I think so but it's completely your decision.
