Attempting to build LED tail lights by using cheap eBay LEDs . 
  
Got my tail lights disassembled . 
 
 
 
  
Here are the LEDs I was going to use . 
 
  
Plan was to have 3 halos on top and 4 halos on bottom with round COB LEDs in each halo . Halos were to be the running lights and top 3 COBs = sequential turn signal and bottom 4 COBs = brake . But the COB LEDs are very bright , it's like looking at an arc welder , and burning way too HOT . It'll burn itself out w/o some kind of heat sinks and fans . So the COBs are out . Awaiting on new LEDs for new design . Really like to keep the sequential turn signal , will see .
