This Mercedes C-class W203 kit contains everything you need to swap your old, blacked-out projectors for powerful new bi-xenon HID projectors. Using the exact same mounting points, 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 E46-r projector is an incredibly bright bi-xenon projector, enabling you to use D2S xenon HID bulbs, including the most powerful options from Osram and Philips. Available bulb colour temperatures range from 4300K to 6500K. You will literally outshine the competition. 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 HID 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. Please be advised, the input is a 9006 type connector, OEM ballasts usually have different input connectors. So you will need to find the Positive and Negative wire which are used for the low beam signal to connect to the input of the ballast. Also mounting will be different. So this requires some DIY. With the Aharon ballasts and 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 HID 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 C-class W203 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 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. The shrouds are held in place by clips that hook into the lens holder (left and right side), these need to be opened to get the shroud off. This can take some force, so please be patient and careful :-).

These products are not ECE-approved and must not be used on public roads in any exterior application. Use on public roads will invalidate both the operating license and insurance coverage.
The product images shown are for illustration purposes only and may not be an exact representation of the product. Actual products may vary due to changes in manufacturing/product enhancements.
The product/kit pictures can differ from what you have received/will receive because we use generic pictures for the kits. Because with all the different options/product changes etc. it's nearly impossible for us to take pictures for all the kits we have and with all the different options. For example, butyl sealant can be shown in the picture, but with headlights that are originally sealed with butyl, it won't be in the kit.
This complete kit has been especially developed to enable retrofitting at home, saving you the cost of installation. However, should you prefer to have a professional carry out the retrofit, you can simply mail your headlights to the nearest participating workshop. They will then perform the retrofit and return the upgraded headlights to you, ready for use.
Please note that, for professional retrofits, you should order your Retrofitlab kit or parts directly from the workshop in question (it saves you money on shipping).
