Mercedes B class W245 (2005-2011) bi-xenon (D1S) - Xenon HID headlights
This Mercedes B class W245 kit contains everything you need to swap your old, blacked-out projectors for powerful new bi-xenon projectors. Using the exact same mounting points, it makes retrofitting quick and easy. And, most importantly, it will take your B class to the next level – just check out the test pictures! This is way beyond what the majority of OEM projectors can achieve.
The Bosch AL E46 is an incredibly bright bi-xenon projector, enabling you to use D2S OEM bulbs, including the most powerful options from Osram and Philips. You will literally outshine the competition. With available colour temperatures ranging from 4,300K to 6,000K, the crystal-clear 3.0-inch lens throws a low beam with a bright hotspot and sharp cutoff. As for the high beam? It’s like the sun.
Such a light output would not be possible without efficient ballasts. If you’re happy with the ballasts that you’ve already got, simply leave them in place. Alternatively, add a set of our Aharon digital 35W ballasts to your order. The Aharon ballast has – as opposed to many other aftermarket units – been tested to generate a full 35W. It 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. The Aharon ballast is also Canbus-proof, so you won’t get any bulb failure readings on your display, and the original beam level system will not require any adjustments. It's the perfect ballast to complement the included Mercedes B class W245 wire harness, which connects directly to the original wiring. Power supply is strong, steady and reliable.
Lastly, this kit provides every single part that you will need for retrofitting. In order to keep the price low, we have however assumed that you will keep your existing xenon bulbs. Depending on how old those are, you may want to also order a new set of bulbs to get the most out of your retrofitted system. Xenon bulbs do lose up to 70% of their maximum brightness over time.
This complete Mercedes B class W245 retrofit kit is inspected by our internal quality control and comes with a solid 2-year warranty. It also includes highly rated technical support from your lighting experts at Retrofitlab.com

This is an easy 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 less than one to two hours.
You do not even have to open the Mercedes B class W245 headlight. Simply remove the existing projector through the bulb access port at the rear and replace it with your upgraded projector. Done.
