I am not certain why it took so long for these to be produced after they were announced as a new product. It seems it took years to get ahold of these lights but the wait was worth it. These are excellent “Z” scales light, true to scale, and the light delivered is also correct to scale. They are well made, have a strain relief at each connection which makes them strong and well made relative to their size. They are easy to install compared to other makers of “Z” scale lighting and with little time and effort you have your light installed. It was a pleasant surprise to find these on the HobbyLinc site at a very reasonable price. I was kept informed as my order processed and had my order, seemingly overnight. Seriously, if you have ordered from them before and did not know how your order was processing, or it seemed to take forever to get your order, I an assure you, it is not that way anymore. Great service, great product! Thanks.
