Need some help from my Forum friends again. I purchased a used Atlas YB RS1 and the light appears to be burned out. How do you go about removing the shell as I am planning to patch out the old information to make it into a new scheme? Also would this bulb be the right bulb to replace the malfunctioning one? I don't run DCC and am no good at soldering so my plan is to use a pigtail of the existing wire, join the new lamp and use some liquid electrical tape on the connection.
As usual, thank you for any assistance that can be provided.
Hi Frrykid, the shell should just lift off with a light squeeze of your finger and thumb around the cab, and then maybe toward the front of the long hood. There are no screws, it's just a friction mount with several tabs. Make sure you pull out the handrails from the holes in the cab before you pull the shell too far away because they stay with the deck. If the original wires are in place you won't be able to run very far with the shell, but it's enough to get at the wiring.

If you have an incandescent bulb currently, that would seem to be correct - if you have the instruction manual that came with the unit I would confirm the specifications with that first.

Unfortunately it didn't come with any sort of instructions or parts breakdown sheet.

When you pop it open, see if you can compare it with any of them available online - I suspect it is this one, but not sure. If it is, it is either very easy or a bit difficult to swap out headlights as they seem to either be soldered directly onto the printed circuit board, or have a retention clip that they slip into. The shell assembly should be fairly similar to what is demonstrated here either way.
Ha! Nerdy, I should have let you go ahead. Yours clearly shows the lamp number. I was only off by one digit, but close only counts in horseshoes and hand-grenades.

I got into the innards of the engine and found the problem why the light wasn't working. Somehow one of the light wires had come disconnected. I fixed the issue and the light now works. Thank you for all the assistance.
Hello All,

If you can get that deep into the loco, I recommend upgrading to an LED.
You can purchase LEDs with resistors included from More LEDs.
They also include printed instructions on how to wire LEDs.
Congratulations on finding the solution.
Hope this helps.

Version 1 appears to be what I needed.
What the problem was is that one wire of the bulb came loose from the contact wire. With a little careful finagling, I was able to put the bulb wire back in contact.
Thank you again for all the assistance. Now comes the fun part - designing and implementing the new scheme for the engine that mostly keeps the existing paint intact.
