Review on 💡 Auxbeam H4 9003 LED Light Bulbs - High-Performance 8000LM 6500K Cool White - F-S3 Series 9003 HB2 P43T Conversion Kits - With Fan & EMC - Halogen Bulb Replacement - Pack of 2 by John Boyce

I bought a set of replacement bulbs for the Aucbeam F-S3 series headlights. Noise isolation turned out to be quite easy and didn't take much time. I would say about 15 minutes for both lamps, which takes up my time. Once installed, you will need to adjust the bulb a little to ensure your low and high beams are properly aligned. Again, this is very easy to do. After installation, you will find that these things are bright. When I say "bright" I mean visible spots when you are in front of a vehicle. They're almost painfully bright, which is a welcome change from the halogen bulbs I had before. So far no problems. If you want good colored bright lights, go ahead. This is a great option. Oh yes, I would also like to mention the excellent customer service.
