Title says real serious tail lights. I run two Whelen TIR3 lights. One Amber One Red and they are synchronized. Power is a very small 12 volt battery and I get about a hr run time. These are serious and one local police officer pulled up next to me and asked me where I got them. I told him Galls, I don't have to go with low bid like you. He laughed. I have them on a toggle switch and use them sparingly when I feel the need in certain circumstances or traffic areas. This isn't the first time I have posted about these, have had them for several years and they do work great and they are very serious.
