Reviews : Model-Power Grain of Wheat Bulb 12-16V 3.2mm Red (3)

these are very bright without wiring them to a dimmer I had bought six of them and one broke during install, but will buy a few more for spares and keep them on a dimmer so they don't blind me

I've used this product numerous times on many HO layouts. Every of section of track is covered with these lights, helps to keep track of the trains.
