Zero S / SR headlight upgrade kit
This Zero S / SR retrofit kit contains everything you need to convert your halogen setup into powerful bi-xenon projector headlight. Featuring custom-made mounting bracket, all the correct wiring and an OEM-style shroud, it makes retrofitting quick and easy. Everything fits inside your existing headlight; the levelling system will work as usual; and there’s no need to cut or solder your original wiring.
You’ll have brilliant xenon brightness on both low and high beam, and the light pattern is sharply defined; you won’t blind oncoming traffic. And, of course, most importantly: this kit will take your S / SR to the next level – just check out the test pictures!
The Optimus is an incredibly bright bi-xenon projector, enabling you to use D2S OEM and D2H 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 wide 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, 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. This ballast is the perfect complement to the included Zero S / SR 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 this kit.
Lastly, this kit provides every single part that you will need for retrofitting – including our handpicked durable OEM-style shroud. Please note, though, that in order to keep the price down, we have only included a decent xenon bulb in the basic kit. For absolute top performance, we recommend that you upgrade to the premium Aharon XB-35 5,500k bulb. This powerful bulb represents excellent value for money, featuring an extremely high light output in a modern white colour.
You may also wish to add a delay relay, which reduces the load on the sensitive electronic circuit by delaying headlight activation until 10 seconds ignition key turn, as well as breathing vents, which prevent moisture build-up inside the headlight.
This complete Zero S / SR 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 Zero S / SR headlights (they’re sealed with butyl, so that’s a quick job), mount the projectors and shrouds, and reseal. Done.
