Many folks have suggested a "Sticky" on upgrading headlights, some to get just some kind of clear lens projector lights, others to put in Bi-Xenons, and others to change bulb color (color temperature).

I have never changed out my headlight units, and pretend to no special knowledge of how to do it - so I am not the person to write a comprehensive guide. However plenty of people have made the various upgrades, and shard their knowledge and experience. Here are the best of the links I have accumulated on the subject, and I hope you will find the answer to your question in one of them.

As a hint: Reading these over, it seems that upgrading from OE standard Halogen units to HID (High Intensity Discharge) units (which have Xenon low beams and Halogen high beams) is not a difficult problem. Similarly, upgrading from OE HID to Bi-Xenon is also not a giant leap. Many problems seem to develop when upgrading from OE standard halogens to Bi-Xenon units. Therefore, as a starting point, one should probably determine what the car has as OE, so as to make a decision on how much time and effort you want to invest. It would also help you to pay careful attention to what model year and type of OE is being upgraded, and to what end result is being achieved, in a particular string - and be sure it matches what you are trying to do. Something that is valid in one approach may not work for another.

I provide the list, but as I said, I have no special knowledge, and cannot resolve conflicts in any of the strings below. Please don't PM me for answers - I don't have them in this arena. But I'll bet the folks who gave the good information below, do.

There is an excellent site that will answer many kinds of questions about differences in halogen, HID and Xenon lighting; bulb colors, whether a given type of upgrade is best, and the like. I suggest browsing it for general discussions - http://danielsternlighting.com/products/products.html

There is also a good discussion on the different types of lighting, including differences in reflector optics for different kinds of bulbs on Wikipedia - http://en.wikipedia.org/wiki/Headlamp

I hope the "experts" in this will add more.

Good luck.

Lights can be opaque or crystal clear; in the U.S., bulbs should be yellow or else silver-coated to avoid egg yolk look, but should show yellow when illuminated.

Replacing my H7 halogen dipped beam with led Cree light

I have replaced my h7 halogen dipped beam on Mercedes w204 with Led Cree h7 light similar to the ones in the link.

It does not remain on continuously when I turn on the light instead in blinks on and off every 5 seconds.

When I installed them on the high beam they worked perfectly.

Can anyone help?

You need some kind of resistor wired in because the led consumes less voltage
