Mercedes C-class W203 (2004-2006) Bi-LED light upgrade retrofit kit for halogen headlights
This Mercedes C-class W203 retrofit kit contains everything you need to convert your halogen setup into powerful Bi-LED projector headlights. Custom-made to fit your existing headlights and including all the correct wiring and a selection of OEM-style shrouds, it makes retrofitting quick and easy. And, most importantly, it will take your C-class to the next level – just check out the test pictures! This is way beyond what the majority of OEM projectors can achieve.
The Aharon AtomLED X2 is used in this kit to ensure you get a powerful output with a good pattern in a compact size projector that fits your headlight. The projector has been designed around LED and has a built-in LED chip. This guarantees a much better output and pattern than putting a LED bulb in a HID Xenon projector like the Mini H1. The LED technology makes the installation quite easy because there are no large ballasts. also, the LED doesn't have a start-up time like with HID Xenon. It also has a crystal clear lens and a modern 6000k light color.
Lastly, this kit provides every single part that you will need for retrofitting and upgrading your headlight – including your selection of stylish and durable shrouds. We offer all the best shrouds compatible with your vehicle you can pick any you like from the drop-down menu (with larger shrouds, some trimming might be needed).
This complete Mercedes C-class W203 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

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 C-class W203 headlights (they’re sealed with butyl, so that’s a quick job), mount the projectors and shrouds, and reseal. Done.
