Hi All... I have sent a couple of photos of the lights. These are great, I have also installed them in my cabooses, they have 3 bulbs in each caboose so I was trying to cut down the amount of power and amps they were using and it DID make a difference, I also installed them in some MTH houses and the Miller beer wagon, and yes no heat. The only issue I have with them is the base of the bulb is more square than the MTH bulb so on some items it is harder to install them. I thought I could just straighten out the wires and reinsert the led bulb into the MTH base but the bulbs are glued into the base. So I ended up just filing back a little of the base each side to make them fit.
Note that the color tint is about 3000K so it's not like the real bright LEDs.
Thanks Arnold
