I have KC slimlights and Rally 800's. Love them. Costly, yes but I couldn't cheap myself. It's what I wanted. If they break Ya I'd feel bad. However I was in a near head on. The front light bar took a good hit. Glass exploded but the housing kept it's shape. They looked like you could have just slapped new glass, seal and a bulb in there and reused them. They were replaced with new.
