"Long time reader..first time poster"
I have an 02 ML 500 with the Bi-xenon headlights. I understand how they work, but I am still confused.
Just inboard of the xenon light there is what appears to be a standard H4 halogen light with the standard reflector. I cannot get it to come on no matter what combination of switches I try. It also has the fog/driving lights that come on when the light switch in in "manual" and the rocker switch is activated. I can even turn on the rear "fog" light in the drivers tail light, but no go on the halogens. I bought this used and I am in the US. Is this a daytime running light that has to be factory activated? It's quite possible that I am just stupid and can't figure out the simplest possiblity. Any help is appreciated.
Thanks, Mark
If you flash your headlights during the day, when your lights are off, the halogens provide the flash to pass. You cant flash a xenon bulb off-on-off due to the fact it needs to warm up....
- and if you want to do half an afternoon's work, you can get them to work as additional hi-beams like on the Bi-Xenons sold in Europe. A very thorough and easy-to-follow description has been published by the Lighting Guru aka Drew here: http://www.benzworld.org/publications/pub.asp?id=67
IMHO, it's worth it.
Cheers,
Birger
PS: Congrats on the ML, and welcome here [:)]

Thanks, I've never looked to see if they flash during the day. I know at night when you flash to pass it does the brights. I never thought to look during the day.
Thanks again.
What kind of difference did the modification make for driving?
Well, considering that you get the HID beam output + another set of halogen high beams, you can imagine how much brighter it is! I have been running the 80 watt Hoen H7 bulbs in there so there is even greater output than the stock 55 watt bulbs [:)]. When you flash someone, believe me, they notice even in the daytime!
