If you are feeding the signals with 12V, the 470 ohm won't be enough. Luckily resistors are cheap. You can buy them from Amazon even.

Here is a handy workaround:

If you have even a basic Volt-ohm meter you can read across the leads and get a good idea of the value as well.
Purple is actually Violet BTW The resistor you have looks like a 5% 470Ω.
Hope that helps, Ed
Hey Guys n Gals, I have a question for you guys, I know I use 1K 1/4WATT resistors for my combo house signals from NJ international, now here's the problem, I wanted to move my signals to a new location, in the process I cut some resistors in half, now I found some resistors that have, they have YELLOW, PURPLE, BROWN, and GOLD bands, I don't know the bands, would these resistors work with my signals??? Thank You for help with this matter, TRAINSRME
