I build custom projectors, ive done many many sets of lights. ill be doing a set for my blazer soon. ill post up a thread with previous builds of mine and the progress of my blazer projector build, as all the headlights offered for blazers/s10s are garbage quality projector units, thin crap housings and cheap 100hr life led halos. I use only oem units, ccfl halos, and I heat test my lenses to see if the focused beam of the projectors or heat of hids will melt the lense.
