Mercedes xenon headlights repair information
Bad light output from your Mercedes xenon headlights?Big chance you are reading this because the light output from your Mercedes xenon headlights is very poor. Therefore driving in the dark isn’t any fun anymore. And as a result safety is at risk for you, your passengers and other traffic. Your car can even fail inspections for instance. But don’t worry, let us help you by explaining what’s the cause and of course the solution. In this blogpost we will explain how you can repair your Mercedes xenon headlights.
The cause…new bulbs?
The reason for the bad light output is not, like often is thought the bulbs. Xenon bulbs will lose some strength, but the real reason can be found on the inside of the projector that projects the light to the street. The projector has a so called ‘reflector bowl’. This bowl is used to reflect the light of the bulb and in combination with the lens it determines the light output and pattern. Because of UV radiation, heat and sometimes a poor design the reflective layer inside the bowl gets 'burned'. The reflective layer won’t reflect anymore and as a result the light output will become very poor.
New headlights? Not a good ideaYou can go to the ‘stealership’ and buy some very expen$$ive original Mercedes xenon headlights. You will get a -decent- light output back for it. But hold on, isn’t it a waste of money to buy 2 complete headlights, when only the projectors need to be replaced? Yes it is!
The best solutionAnd that’s why we have the best solution, you can repair your headlight by replacing the original worn-out projectors. - The Aharon replacement projectors offer an (almost) plug and play installation. - Because of years of development and the latest xenon technology the projectors will also perform better than new original headlights. - Replacing only the projector is very cost effective. - Because the projectors are bi-xenon, the high beam function is also available. With the Aharon bi-xenon projectors you will have a bargain and better light output in comparison with new headlights.
Installation is usually a breezeWe hear you thinking; the installation that must be hard!? Well, usually it isn’t! A lot of Mercedes xenon headlights are designed so the xenon projector can be replaced from the rear of the headlight. So when you can handle a screwdriver and look up some info on the internet on how to remove the headlight, you are certainly good to go.
AFSFor AFS headlights replacing the projectors is a bit harder. This system turns the projector to the left/right depending on the steering position. These systems can be mounted to the Aharon projectors. The EvoX-r is the best option because it has the correct mounting points. The EvoX-r 2.0 can also be used, but the holes to mount the AFS system need to be drilled for example. When the headlights have the AFS option, it usually also means the headlight needs to be opened and the projector can’t be replaced from the rear. In case of AFS, the D2S extension cables are not needed. On some occasions, it is needed that the AFS system is re-calibrated by the Mercedes dealership.
D2S extension cables
The Aharon exclusive D2S extension cables can be used for carefree mounting when originally the Hella D2S igniters are used on the E55 projector. They are not needed when the headlights use D1S bulbs, has AL 46-r projectors or has AFS.
