Code 3 Led Lighthead B. Condition is "Used" only because I purchased this new and tested it before I put it up for sale. I currently have this exact same lighting mounted an echo 21 series a code 3 2100 and a code 3 21tr they are the end led that sit at about a 45degree angle I've heard them referred to as the tarus but I am not 100% sure as long as you have the two wire plug that goes to it it will work it is self grounding any questions feel free to let me know
