[quote]QUOTE: Originally posted by tstage I ended up replacing the "green" LED in my 2-8-2 Mike with a 3mm T1 golden-white LED this past evening. It was actually a very straight-forward install. I popped off the front cover, unsoldered the green LED, soldered in the golden-white LED, insulated the bare wires with heat shrink, popped the front cover back on and - Wallah! - brand new head light! Let me tell you: <center>IT ABSOLUTLY LOOKS GREAT! [:D]</center> I thought I might have to replace the resistor that was on the circuit board but the LED is working fine. The difference between the two is no comparison! This is a definite must have in either the Mike or Challenger. I don't know if the same will be true for the Challenger, but, as I said already, this one was a piece of cake to replace. I picked up my LED at Litchfield Station for $1.50, when I was ordering the decoder for my S1 switcher. You can probably fiind one at a Radio Shack in your area. Do it! You won't regret it! Tom [/quote] The resistor that I installed in the Challenger was to lower the brightness of the number boards only. The two LED's for the number boards are built into the number boards and can't be changed out. If you lower the voltage on them, they really look good. The headlight does not have a resistor in the circuit and you are correct, they really look good when they are replaced. I am sure it was a great improvement on your Genesis 2 8 2 also. It is an easy change on most engines, but the Challenger is a bit more difficult because of the location of the LED in the front engine chassis.
