Also, I want to touch on safety and the use of proper protective equipment when handling power tools. When I was installing the OEM halo ring over my LED halos I had to cut the bottom portion of the OEM halo so that it would fit in front of the LED halo. I attempted to cut the plastic halo ring with a sawzaw. BAD IDEA.
I ended up cutting my thumb pretty bad from the splintering/melting plastic. Took a safer route and used bolt cutters. Much better idea, worked like a charm and no further injuries.
