FinnerZ Posted November 7, 2011 Share Posted November 7, 2011 Just a quick question about a the directional lighting in DCC converted trains - I know that running a DCC train on DC won't let me turn the lihts on/off etc. but will they come on in the direction of travel or just not come on at all. And also is there a CV to change the brightness of lights (change output power)? Link to comment Share on other sites More sharing options...
Southernman777 Posted November 8, 2011 Share Posted November 8, 2011 FinnerZ,Hi. Yes the lights change direction as you'd expect. I run my DCC locos on DC and the white / yellow lights up at the front and the red lights at the rear. The lights change with the change of direction.I don't know the cv answer but would be interested to know. Some of my decoders come with lots of instructions that I have not time or the will to read. One has 64 pages! The one I purchased last is very good but has German instructions? Goes very well.Have fun. Link to comment Share on other sites More sharing options...
Rog RJ Posted November 8, 2011 Share Posted November 8, 2011 Many decoders allow function outputs to be dimmed, including the Hornby Sapphire which uses CVs 117 to 120 for this. Other decoders may use different CVs. The basic Hornby decoders don't have function dimming.The Sapphire manual is here https://www.hornby.com/filelibrary/download/?FileID=138 Link to comment Share on other sites More sharing options...
FinnerZ Posted November 8, 2011 Author Share Posted November 8, 2011 Thank you very much for your answers. I have a stash of basic hornby decoders that came as a part of a larger package so I might just try out a resistor if the interior lighting is too bright.

Southernman777 Posted November 10, 2011 Share Posted November 10, 2011 Rog,Thanks. I'll give this a go as I have a mixture of decoders including the Hornby Sapphire.Kind regards, Link to comment Share on other sites More sharing options...
FinnerZ Posted November 12, 2011 Author Share Posted November 12, 2011 After a few problems (such as realising my decoders are in my grandparent's garage half an hour a way, and the circuit boards for the lights snapping), I have managed to wire up the directional and interior lighting in the trailer car to a minature plug to go to the driving unit. However, my biggest problem now is deciding wheather or not to add a resistor (loads came with the white headlights) to the interior lights circuit as they do seem very bright even with just a 9 volt battery. My dad has travelled on suburban trains for many years and recomends the dimmed lights, but I just wondered what forum users thought. Link to comment Share on other sites More sharing options...

You can always use a separate decoder on the same address in the trailer car. Link to comment Share on other sites More sharing options...
