I want to replace the amber head lamp on my 3 Bachmann Heislers.  Can someone please give step by step instructions how to access the bulb?

Thanks

That's incorrect Fred!

The suggestions provided on the site you listed were just that.  There was NO definitive answer which is why I posted here on the Bachmann Trains site thinking that the experts here might have the definitive answer...  Right??
