Yup - the relays make the "bulb-out" idiot light come on. But it doesn't come on when I turn on the city lights (triggered by my old fog light switch). So if that teeny city light bulb can make the sensor happy, I think I can find a way to fool it with a proper sized resistor in parallel with each relay coil. I'll be doing more research on that.
UPDATE: I had BergWerks modify my "bulb out module", which cost about $80. That works great! Also, I believe the fog light circuit (now my city lights) does not trigger the bulb-out light, even on a stock 124. So the city light bulbs weren't keeping the module happy, the module didn't care in the first place.
If you go Xenon, meaning the H4 HID replacements that are ~$500+, you can now get ones that have high & low beam. Or, you can get 500E Euro lights from PUMA that have a driving light instead of the fogs (like mine). Then you use HID for the H4/low beam, and use the H3 driving lens for high beam (and/or flashing). Using your fogs won't do much, the lens creates a wide, flat, low-aimed beam. Then you put fogs down in the lower bumper, where they belong in the first place (and where the 500E has them from the factory.)
