I installed these with a set of their Headlight bulbs in my coworkers 2011 Tacoma and holy cow it made a huge difference. They seem to be well built and fit perfect. Also the light output is incredible. I have a feeling that these are going to last for a long time but time will tell. I have some of the small amber 194 amber bulbs in my 2003 Jeep Grand Cherokee and have seen zero issues with them. Also, Auxito is the only company that I have found so far that makes bulbs that fit in my co-workers Mercedes 2012 C300. He has been super happy with the bulbs he bought. 3 reviews in one and 3 happy customers.
