Are there any negative effects on using a R2LC07 in place of a R2LC08 in a basic engine? Headlight and rail sounds only, and primary operation will be conventional. The headlight is a normal incandescent bulb. I am using a 691-PCB1-0B9 motherboard. This is a project for a friend of a friend. I don’t want to lose my R2LC08 and they have a R2LC07. 

 

There shouldn't be, the incandescent bulb won't care about polarity.  You'll never know the difference.

Thank you!

Can I use a R2LC07 for an 08?  

Yes and no.  While many of the functions are similar, one standout difference is the polarity of the lighting outputs, the R2LC-07 has positive in respect to frame ground, the the R2LC-08 and later have negative outputs in respect to frame ground.  This causes issues in many locomotives, especially those with LED markers and/or headlights.
