How are these different than the RGBW chasing halo pods that are on for $119?

Hi,Thanks for your inquiry,the RGBW chasing halo pods is 20w,this pods is 40w,It'll be brighter,So its more expensive.

I have rgb halos installed in my truck already and they look to use the same remote and harness as the ones pictured here. Could I wire these pods in to my exsisting harness so that they would all run off the same remote?

Yes, you can if you confirm use use same app magic led

I have rgb halos installed on my truck and the remote, reciver look the same. Could i wire these rgb pods into the same harness and run them with my existing receiver/remote?

yes, do you get same app called magic led, if so, you can use one app to control all lights
