You can probably use a 1/4 watt resistor. This one is pretty big.

I was gonna say that LED supply is great when you just need one or two, but I just checked and they don't appear to have 4.7k in stock:

https://www.ledsupply.com/led-drivers/resistors

Maybe an email to them would be worth it, they do appear to have 47, 470, and 47.5k, so I don't see why they wouldn't keep 4.7k in stock.

Mouser is another good source of parts.  If you have the tools I would go with an SMD
