Does the Loksound 5.0 decoder #58821 need a resistors for LED headlights?

I am preparing to install a Loksound 5.0 decoder #58821 and will be “hard-wiring” it since the engine has no motherboard (replacing a 3.5 micro). Do I need to use resistors for the LED headlights, as in other “hard wire” installations? Thanks for any help.

The Loksound 5 manual should have a diagram of the decoder and where the soldering pads are located. I see #58820 listed in the manual but not #58821? Is it a Loksound 5 micro?

It looks like you will probably need to use a resistor. Do you have a spare LED & resistor that you can temporarily solder to the Loksound 5 lighting pads to test it?

[Update: Pg. 35 states that you do need resistors when using LEDs]

58821 is the Loksound V5 Direct. It’s newer than the general Loksounf V5 manual that is currently on the site. Just looking at the pictures, it appears there are resistors for at least the front and rear lights with solder pads to jump around them if not needed. If that carries over to other function connections, can’t really tell. It’s also not easy to see the value of said resistors in the picture.

Thanks, Ed & Randy. I wish ESU would update their website for the latest info on their Loksound 5 decoders. [:S]

Thanks to all who responded. Ed’s reply answered my question quite well. My package with the decoder did not include this paperwork and the 5.0 manual is not up-to-date as yet.

Later tonight or tomorrow I’ll scan the rest of that quick reference sheet for you, John.

Just in case.

Thanks, Ed! Finished the installation–no resistors needed; set speed parameters yesterday and engine is ready for service! I appreciate your help. BTW, I discovered during installation of sound files that #588221 DCC Direct is actually a micro 5.0 on a board (converted by Lokprogrammer during installation). Sounds and runs great!
