Thanks all for the responses. 
I went ahead and tried the car and so far all is well.  You guy's were right on in that the lights are quite brite.  So far heat doesn't seem to be an issue.  We'll see how long they last.  Thanks for the help.

I've been told not to attempt to put lighted Bachmann passenger cars on a DCC layout.  Can anyone out there shed some light (no pun intended) on why this is a bad idea?
