I have had these LEDs for almost a month and feel satisfied as this is my first time using this product. I converted from 9005 halogens to HB3 6000k LED bulbs and they fit perfectly in my projector headlight housing for a 2019 Chrysler 300s. Upon opening the package, foam like insulation surrounded the bulbs securing and protecting the LEDs. Installation was straight forward and my vehicle did not require a ballast, but my headlight housing covers required several strikes of gentle tapping with a pin and hammer to remove (don't break those fins off). This is a common problem with Dodge/Chrysler vehicles as the rubber sesals dry out over time. Similar to the stock halogen pattern, RCJ's beam pattern is tight with minimal to zero glare. The small fan does give off some humming noise that does not bother me and provides some peace of mind hearing that my headlights are being cooled.Amazon pricing is very competitive as compared to a pair of halogen bulbs which would have cost about $5-6 less. This item is described accurately by the seller.
