All TYC lamps are subject to vehicle test fit and other procedures to assure top quality. TYC lamps conveniently offer "drop in fit" with comparable tolerance, virtually identical mounting provisions and interchangeability with OE wiring harnesses. TYC lamps are engineered to meet or exceed OEM specifications.

For extra confidence, some TYC lamps are certified (denoted in catalog) by independent, third part organizations like CAPA or NSF who guarantee fitment and quality equal to original equipment.
