One of my locos that I want to decoderize has 1.5 volt globe directional constant brightness lighting. (uses diodes/resistors on the internal circuit board) Lighting at each end of the loco is headlight, and red/white marker lights. Forward has white marker lights and headlight, with red marker lights at the rear. Lighting is reversed when direction is reversed. This is on DC.
There are 3 1.5 volt globes at each end. ( 1 for red marker lights, one for white marker lights, and one for headlight).
The globes are mounted into the chassis, with "funnels" (if that's the right word) on the body that"funnell" the light to the appropriate marker lights etc. I really don't want to pull this mechanism apart. I really should put a pic of it up, to help describe it, but never mind.
If I just wire the decoder up for motor only (into the relelvant point in the loco), will the constant brightness lighting still work properly? i.e. do NOT wire up the decoder headlight functions. Although it would mean I cannot turn headlight on/off, nor have the lights on when stationary.
But I see no reason why the DC current supplied by the decoder would not also power the constant brightness directional lighting as well. The draw of current by the motor & lighting from the decoder shouldn't exceed the capacity of the decoder. The decoder (NCE D13SR) is rated at 1.3 AMPS.
Any thoughts? I don't think I'll blow the globes, or constant brightness circuity, as it's designed for 12 V DC anyway. (I run a DCC track voltage of the default of 14.5 V AC)
