THE START OF SOMETHING BIG
Years ago there were no formal sources for retrofitting components. You would have to get a damaged headlight off of eBay or from a salvage yard, extract all the parts from it yourself and design and put together your own wire harness. There were no guarantees on the internal or working condition of these parts, and they were expensive too. You want a set of OEM [plastic] projector shrouds from a BMW E46? $200. A set of OEM clear lenses? That'll be another two bills. You haven't even purchased the core components for the retrofit yet. How about some Acura TL projectors? 300 bucks. Decent condition used OEM ballasts and Philips light bulbs: $200 please and thank you sir. And thus, The Retrofit Source was born in June of 2005.
Originally specializing in collecting and supplying the hard-to-find HID headlight retrofit components, we started out as a company who purchased and recycled slightly damaged headlight assemblies in bulk from salvage yards around the US. Everything salvageable was cleaned, tested and sold; only to realize road-use once again in a retrofit. Eventually we developed our own purpose-built lineup of parts. Starting with the high-demand parts that could be used across the board such as our E46-Replica shrouds or ZKW-Replica lenses, they were an instant hit. Offering OEM-like performance on an aftermarket budget, we expanded the lineup to include other necessities such as ballasts, bulbs, wire harnesses, and of course projectors. All of these components were conceptualized and engineered in-house and ultimately became the foundation for what we are today!
