Nissan Frontier LED Headlight Conversion Kits

Received these LED bulbs and could not figure out how the lock ring that secures the bulb to the housing would fit over all the cable, electrical box, and rear housing. Called CarID - initially to return the product, and got great support that helped me get these installed. I could not find any instructions for installation, nothing came in the packaging, nothing on the web either. What I found out through CARID was that the upper flange is removable so the Lock Ring can install over the bulb, very different than how this works on the stock halogen bulbs. It would be impossible to figure this out without the guidance. The flange is very secure and takes some effort to remove, and does not look at first like it is removable. Once the flange is off, slide the ring in place, pinching the cable tight to the housing, and reseat the flange. This can be a bit challenging since everything is very snug, but with some patience and effort all will lock together and the bulb can go into the housing and lock in place. I used some zip ties and existing holes to hold the control boxes in place. Very happy to have gone through all this and have these installed. Very clean, bright light. Bulbs and cables are very well made and seem high quality. Only knock I can give is there should be some sort of instructions included in the packaging, or at least posted on line explaining how to install these. Big thank you to CarID for walking me through all this , and kudos to excellent customer service. I am already looking to buy more lighting products from them, and will certainly return often for more upgrading.
