If your looking for a D3S upgrade or the H11 upgrade don't waste your time looking elsewhere. I was hoping to put some more hours of driving up on these bulbs before doing a review but I can honestly say that you will not find anything else out there unless Auxbeam upgrade these bulbs. The box they came in was like a jewellery box I said these boys have presentation. The quality of these bulbs are absolutely first class. Solid as a rock. When fitted worked straight away, no flickers or errors. Now the most important part is, f..k these are bright genuinely turning night into day. I could go on and on but there is no point. I only can recommend the bulbs which I bought but I've a feeling that Auxbeam are going to be around for a very long time. Hopefully soon I can get some 7" 360 pro series and see if they are as good as people say.
