Okay I am officialy clueless. I have a 99 E 300 TD and want to upgrade to xenons. I bought a set of used oe xenon lights off of ebay and just for giggles plugged them in and to my suprise they lit up and no error message.

What is going on and should I be worried about a fire?????? Everything in the car is stock and it is non-xenon. Please let me now... Thanks

George

The prior owner of my '98 E300TD did a xenon retrofit. They seem to work fine and are very bright, but they do (sometimes) trip the "Defective Lamp" warning. I just ignore it at this point. The wiring all appears to be stock.

Are the lights you bought reflector or projector beam? More info, please!! I wish mine had bi-xenon projectors. Thanks to a fellow here on the forum I know how to retrofit, but just haven't got the time, money, or guts to do it right now.

Cheers, John

All I did was replace the stock lights with xenon stock lights and used my connectors and they light up with no warning message or error. Please let me know if this is acceptable.

How do you properly do a xenon retrofit to my 99 mb turbo diesel???

I'm guessing you're probably fine. HID bulbs and ballasts typically draw less power than halogen or other filament lamps, so there should be less load on the wiring overall. Were xenons a factory option? If so, I'd bet that M-B wired the car for the highest load possible, rather than using different headlight wiring depending on which light units went in the car. It's cheaper to use the good wire in all units than to constantly switch back and forth.

Now...tell us more about the headlights you bought, per my previous post, please!

Cheers, John

You can get rid of the occasional lamp warning by coding the system to tell the car that it has HID lamps.

But you really should have levelers with those infernal things.
