I had really high hopes for this product, and with the Kato brand reputation, I thought that was not unreasonable. I even bought seated people from Hobbylinc, painted them black, and fit them into the passenger car seats for added realism (I had to cut off their legs, lol). I really do not know what to do with this seemingly terrible product - please see my photo of the uneven lighting. It has extremely poor electrical conductivity to boot, and only works if I press the car to the rails. I could solder little wires in for 100% contact, but my biggest problem is the unrealistic lighting that this product gives. I just cannot get past something that makes the model look fake, and I am very surprised that Kato would not address this - since this is the 2nd version of the product. To boot, the lighting kit parts do not fit seamlessly with the Kato brand passenger car. I've been tinkering around with this thing for 2 hours, just to get one car lit (when I press on it). I've had to bend electrical contacts because the factory configuration did not fit the width of the lead pins from the PCB - by the way - you'll have to do that to so that these will work I bought 2 kits. Hobbylinc - You've got a kit coming back I guess the one I opened I am stuck with, so maybe eBay?

Very satisfied with end result. Took some fumbling around on my part to get it right. The Bi level cars are the easiest.

This lighting kit worked so well, I painted and populated the inside of all my passenger cars because now they can be seen. I found this kit easy to install. That is partly because I chose not to use the color filters. I don't really see any blue light. I have watched the filters being installed on YouTube videos which show complete installation and it does look a trifle difficult. I have read a 1-star review of this product that says that the lights don't come on unless you push on the car. This is not the case if the kit is installed correctly. My lights work fine as my pictures show. Also, if the light is not diffused to the other end of the car, it is because the diffuser is improperly installed. Upside down would be my guess. When installed correctly, This simple kit adds a dimension of realism to your layout. I highly recommend it to people who never assume that they did it right the first time.
