Hello and Welcome to the Forum

With DMUs and running on DCC , to have lighting that is independent , so that the Tail lights can be switched off independent of headlights the light s must be wired to different functions.

Not sure about British outline DMU's , But if the DMU has Head and Tail lighting on both ends of one unit then a TCS 4 function decoder (T4X) will do the job if it can physically fit in the DMU

Function 1 -headlights on one end
Function 2 - headlights on the other end
Function 3 Tail lights on one end
Function 4 Tailights on the other end

If the DMU is part of a Pair (lights on each unit , but only on one end)
Then a T1 will do for the powered unit
Function 1 -headlights
Function 2 - Taillights

and a Stationery Decoder (No motor control ) or Fleetlighter decoder on the non powered unit TCS have a FL2
Function 1 -headlights
Function 2 - Taillights

Or use a FL4 and use the extra functions for Internal lighting This is what I did for an unpowered DMU using the DCC Concepts Flicker Free lighting unit -- Details Here

LEDs are the best for lighting , but each must be wired correctly with Resistor in series (1000 Ohm is a safe option)

The Long leg of the LED is connected to the Blue (+ve) wire of the decoder

Hope this helps

You can buy a TCS T6x decoder that has 6 functions

Decoders can be given the same address , that is what I did with my DMU's each pair has the same address no.

A bit amusing if you put the wrong dummy end with the powered end

The Functions can also be changed to be activated for different running conditions , going forward , going backward , which function button activates the function etc

We can help when you get that far

Hi locoworks

Don't worry about it , I answered the same time (roughly) as Edwin and covered similar ground without realizing , these things happen
