H16's listed on the web show a totally different bulb base then the H16 I pulled from the car. I had purchased H11's in the past and they don't work when I try to plug them in. Does anyone have experience replacing to LED's and my questions are: 1. What is the proper bulb number (Instructions say H16 but the LED H16 look nothing like Prius H16) 2. Where did you buy this bulb 3. Was any modding necessary to make it fit into the pig tail/plug? Thanks!
