This Mercedes R-class W251 retrofit kit contains everything you need to convert your halogen setup into powerful bi-xenon HID projector headlights, it makes retrofitting quick and easy. And, most importantly, it will take your R-class to the next level – just check out the test pictures! This is way beyond what the majority of OEM projectors can achieve.
The EvoX-R 2.0 is without a doubt the brightest bi-xenon projector our light meter has ever gauged, enabling you to use D2S bulbs, including the most powerful options from Osram and Philips. You will literally outshine the competition. With available colour temperatures ranging from 4300K to 6500K, the crystal-clear 3.0-inch lens throws a wide low beam with a solid hotspot and sharp cutoff. As for the high beam? It’s like the sun. Also the original leveling system keeps working.
Such a light output would not be possible without efficient ballasts, and the included Aharon digital ballast has – as opposed to many other aftermarket units – been tested to generate a full 35W. The Aharon comes in a rugged and extremely compact housing perfect for retrofitting, and its in-wire starter warms xenon bulbs in as little as five seconds. It is also Canbus-proof, so you won’t get any bulb failure readings on your display. This ballast is the perfect complement to the included Mercedes R-class W251 wire harness, which connects directly to the original wiring. A high beam splitter is also included, making for easy integration of the bi-xenon mechanism. Power supply is strong, steady and reliable.
The Aharon ballast ensures that you get maximum possible light output. However, any ballast with AMP connectors is technically compatible with kit. Lastly, this kit provides every single part that you will need for retrofitting. With the regular bulbs you will have basic performance, with the XB version you will have a better performance, but for absolute top performance, we advise that you upgrade to one of the premium Osram bulb options.
This complete Mercedes R-class W251 retrofit kit is inspected by our internal quality control prior to shipping and comes with a solid 2-year warranty. It also includes highly rated technical support from your lighting experts at Retrofitlab.com

We look forward to brightening your day (not to mention your night)!
This is a fairly straightforward retrofit that even complete novices can do, but those with more skills and experience will be quicker. Discounting removal and replacement of the headlights, you could expect the job to take anything from one to three hours.
Simply open the Mercedes R-class W251 headlights (they’re sealed with butyl, so that’s a quick job), mount the projectors and shrouds, and reseal. Done.
