Sorry if this has been addressed, I am new and want to get my first DCC engine and a controller.  I like steam engines and I'm looking at the one above.  Comments?

In particular, I've seen some comments that the lights may not work well... anyone agree/disagree?

If they don't, how easy or hard is it to change them on this engine.... keeping in mind I've never really wired anything and I'm completely new to the hobby?

Many thanks.
